Thank you for your time
Survey method explained:
After coming to the conclusion that I will create a survey in order to gather information and data based on my hypothesis, I began the process of constructing it. I decided that I would use Ms Office word to create the survey as it was an appropriate software to use to create the survey, you can add text, add headings, and add response boxes, what more do you need to make it look professional?
I decided that I would record what age group they fit into, their gender and also where area they were from, so I created response boxes for each one except ‘where area are you from’ , this was because I left It open, as there are many areas in the UK a person could be from.
I then thought about my questions, I used a piece of paper and a pen to jot down ideas and what type of questions I would use.
I came to the conclusion that I will divide my survey into three separate sections, each section simply for each hypothesis. I based each and every question on that particular hypothesis stated for that section. I did this taking into account that I can use this survey in addition to drawing a conclusion to each hypothesis, and also took into account that it will be easier for me to conclude the results in a later stage.
Once I completed my survey, I printed it out and trialled it on a friend to see if it would work, and see if I can talk along with it. I prepared my self with a speech that I would use to approach someone in a polite manor. Once I was happy with my survey I decided that I would photocopy twenty, I decided to survey twenty people as it was a reasonable sample t work on, not too big, yet not too small.
On the 12th of December 2008 at roughly 9:30, we went to Stratford to carry out our surveys. We decided that we would carry out our surveys around surrounding areas of the Stratford shopping Mall, the back entrance of which is adjacent to the bus and train station. This was a key location as commuters would pass this area to gain access to the new Stratford city, not only that, but we knew we’d bump into people who live and work in Stratford, these were the key people that we needed to hear from.
I realised that many people were keen and had an interest in what we were doing, and approached us instead, this showed an enthusiasm in the person and I took my time to explain to them stuff that they did not know about the city, I managed to take the best opinions from these people. There were many people that I realised that were in a rush to get to their destination, these people I avoided as I knew that they would either say no, or do the survey in a rush.
We completed our survey data collection at 12:30pm. We then headed back to our school and looked through our results, we created tallies and analysed our results, and we also compared our results with other people.

Group interview with project directors, managers and Project representative
of Stratford City/Olympics village.
This was an amazing opportunity for us. On the 4th of March 2008, 9:00am, we departed to the Stratford City redevelopment site. We were accompanied by our teacher along with Paul Cannons (Stratford City Education Development Officer). We were escorted by a privately hired coach and were led to Stratford station where we met Justin Jones who is in charge of the continental transports, Jonathon Watson, Who is the manager of Westfield and Tim Lease who is in charge of the future Olympics Park. We were led by the men to the site, where we had a coach tour of the site; the men acted as tour guides and briefed us about where different buildings such as the shopping centre and School will be located. We were then taken to the proposed Stratford international station, where we toured the building, looked down at the platform and watched as Euro star trains passed below us, through tunnels which led to Europe. The three men then gave a speech and gave a briefing on a PowerPoint presentation based on the plans and developments of the city. Student learned and jotted down many new facts about the future city, which will host the Olympics in 2012.
We also gathered some information and facts, when a Stratford City representative came into school, and gave us a speech followed by a presentation.

Environmental Quality Index (EQI)
Figure 15
It was hard to find a road to carry out an EQI survey on. I eventually came to a conclusion by using Google maps to pin point a road, I carried out my EQI on Leyton Rd E15, the road was adjacent to the site, and was perfect because my results would be precise. I carried out my EQI by using the ‘street view’ device on Google Earth, this piece of software is very useful because it shows up to date images of the area, and is exactly like how you would walk through the street.
Figure 16
I obtained this aerial image of the area that I carried out my EQI from the Google Earth software. You can see from the map that Leyton Rd is adjacent to the redevelopment site, it borders part of the north end of the site, where the Athletes village will be located along with the 8700 houses.

Traffic Survey (T.S)
I gathered the traffic survey results from a class mate, she used a traffic survey that was provided, she stood on a road which led into Stratford and counted the different types of vehicles going into Stratford, she then multiplied this by 12 to get the result of vehicles going into Stratford in an hour. She then carried out the same procedure for the vehicles going out of Stratford. I used her data to create a summary table.

Data Analysis and presentation for Survey
Once I got my results from my survey, I analysed it and created a frequency charts for each question using Ms excel, I then created a chart for each question. I based the type of chart depending on each question. On the next few pages I will present each chart, and explain why I used that particular chart for that question. I will also analyse the results.
This is my graph for the age groups (Analysis):
From the graph you can see that I did not survey anyone under the age of fifteen. I managed to survey six people who were aged between 16 and 25, 8 people aged 26-35, 3 people aged between 36-45 and only 2 people aged 46 and over. From the bar graph you can see that the majority of the people that participated in my survey belonged to the 26-35 groups. The minimal participants were the group aged under 15, I believe this was because of the time, 9:00-12:30, this was school hours hence no participants. When analysing my results, I realised that I did not get an equal opinion from each age group, this could effect my conclusion. I thought of re-doing my survey, but thought that this was an uncontrollable factor, as it would be rude to approach someone and ask their age, and then say that they cannot do the survey because of their age. For this very reason, I did not forward with the process.
Why choose this type of graph (Presentation):
I chose to use a bar graph for this question because the age group is a categorical factor, using a bar chart when there is categorical data such as age is involved is the best possible option.
This is my graph for ‘gender’ (Analysis):
When doing my survey, I took into account that I should be able to control some variables, in order to make my data less biased yet more valid. One of the variables that I was able to control was the number of males and females I would survey. I decided that I would survey the same number of men to women.
My total numbers of participants were 20 people, so I surveyed 10 females, and 10 males. The graph above represents this.
Why choose this type of graph (Presentation):
I chose to use a bar graph for this question as well, fro the same reason I chose to use a bar graph for the first question. I was dealing with categorical data such as male and female, along with frequency. A bar graph is the best type of graph for categorical data, as it is easily understood.
Pie chart for the question, ‘where are you from?’
Figure 21
Analysis:
I took a note of where each person that participated in the survey was from, using this result I could analyse where people come from to facilitate the needs that Stratford provides at the moment, I could also use these results to estimate how many people would come in the presence of the new city.
You can see from the pie chart that 40% of the people I surveyed were from Stratford itself, 30% from Forest Gate, 20% from Plaistow, and 10% from East Ham, all of which are neighbouring areas except Stratford (see map on Page 26).
Why I used a 3D pie chart to plot this data (Presentation):
It is easier to analyse because of the colours, and also the addition of the percentages is a bonus. 3D pie chart is better than a 2D pie chart because it looks more graphical and nicer.
Below I have added a map which I got of Google maps; I have added this map to back my point of the fact that the following areas annotated in the map are neighbouring areas of Stratford. All of the following areas are within a five mile radius of Stratford.
Figure 22
The next four questions are from section one of my survey, these questions are based on hypothesis one.
Pie chart for question 1 of section 1
Figure 23
Question 1: Do you know about Stratford City?
Yes: 13
No: 7
Analysis:
I chose to do this as my first question, so that if a person did not know about Stratford city, I would give them a little briefing about the city, before we carried on with the survey which could only be answered if the person knew a little about the redevelopments.
From the pie chart above we can analyse that a higher percentage of people knew about the redevelopments, to be exact, 65%.
Why choose this type of graph (Presentation):
I chose a pie chart for this question because I realised I was able to add percentages which was good, and because it is easy to analyse the percentage difference.
Bar Chart for question 2 of section 1:
Figure 24
Question 2: Do you think that the developments will have a positive impact?
Yes: 12
No: 8
Analysis:
From the graph you can analyse that more people thought that the city will have a positive impact upon them. Twelve people said ‘yes’ and 8 people said ‘no’. The results to this question prove that hypothesis one is correct.
Why choose this type of graph (Presentation)
I chose to use a bar graph for this question because it was a closed question, like the majority of the questions in my sample. A bar chart is easier to analyse when you only have two dependent factors.
Pyramid Graph for question 3 of section 1
Figure 25
Do you think that there will be more negative impacts than positive ones?
Yes: 9 No: 11
Analysis:
This question was a key question in my survey, I am basically asking the participant whether they agree with my hypothesis or not. The results to this question will play a key role when it comes to drawing a conclusion to hypothesis one. My results prove that the majority of people who commute through Stratford on a regular basis believe that there will be a more positive impact, proving my hypothesis to be correct.
We can see from the graph that more people disagreed with the idea that there will be more negative impacts than positive ones. This result backs hypothesis one heavily.
Why I chose this type of graph (Presentation):
The pyramid graph uses the same axis as a bar graph, except it uses 3D pyramids instead of bars, which makes it look more sophisticated. My variables were categorical, ‘yes’ or ‘no’. A pyramid graph is easier to analyse.
Pie chart for question 4 of section 1
Figure 26
What type of negative impact will be the highest of concern to you?
Rubbish: 4 Greenhouse Pollutions: 8 Crimes: 7 Overcrowded: 6
Analysis:
Once a participant answered question 3, I needed to know what type of negative impact people are most worried about.
You can see that the majority of people are concerned about the emitting of greenhouse pollutions, on the Official Stratford City website, Westfield has noted that, “75% of all Stratford City's electrical power and will be met through the construction and operation of an on-site Combined Cooling, Heat and Power Plant (CCHP). The 'Stratford City Energy Centre' includes a biofuel boiler to ensure that a proportion of the power generated is from a renewable resource”. If I was to tell this to my participants, then they would have had a different positive view about Stratford city, a more positive impact. This proves Hypothesis 1 to be correct.
Why I chose this type of graph (Presentation): I chose to use a Pie chart for this question because I had more than one variable; I wanted to also add the percentage function to compare percentage differences.
The next four graphs will represent the answers for section two of my survey. Section two contains questions based on hypothesis two; this section will contain questions that focus on the economy.
Doughnut chart for question 1 of section 2:
Figure 27
Do you believe that the developments will have an impact on the economy of the area?
Yes: 16 No: 5
Analysis
Here you can see that 76% of the people I interviewed believed that there will be an impact on the economy of the area and 24% believe that there will be no impact. The majority believed that there would be an impact on the economy of the area because of the large scale retail shops, the new jobs and the housing opportunities, all of which are positive, therefore proving hypothesis two.
Why I chose this type of graph (Presentation):
I chose to use a doughnut chart to represent my data because I wanted to find and then compare percentages, alternatively I could have used a bar graph because I had two variables, which I could have compared the frequency, but I thought the doughnut chart was better.
Bar graph for question 2 of section 2:
Figure 28
What sort of impact do you think that they would have on the economy?
Yes: 16
No: 4
Analysis:
In question 1 of section 2 of my survey, we asked participants whether they thought that the developments will have an impact on the economy or not, some answered yes, and some answered no, however we don’t know what type of impact they have in mind, positive or negative?
This is the very reason as to why I created this question.
From the bar graph you can easily see that the majority of the participants thought the developments will have a positive impact.
16 people believed it will cause a positive impact, 4 people believed that the developments will cause a negative impact. This shows that the majority of the people believe that hypothesis two is correct.
Why I chose this type of graph (Presentation):
I chose to use a bar graph to present my data because my variables were categorical; it was either positive or negative. From my statistical knowledge I know that when you have categorical variables, a bar graph is the best to use to present the data.
Pie chart for question 3 of section 2:
Figure 29
Do you think that new shops that will open within Stratford city will out business the current shops within Stratford shopping mall and surrounding areas?
Yes: 7
No: 13
Analysis:
This is a very hard question and people took their time to think about it, many had their reasons such as, ‘the shopping centre is the first thing you see when you come into Stratford bus station, im sure they will be hand in hand’. Other responses included, ‘The current shops are known too well to be forgotten’.
From the pie chart above you can see that 65% disapproved of the statement, and 35% approved of it. This shows that the public do not believe that the old shops will lose money therefore; there will not be a loss in economy, and the new shops will boost the economy, meaning the economy of the area will improve, hence my hypothesis two is correct.
Why I chose this type of graph (Presentation):
I chose to use a Pie chart to represent my data because I wanted to compare the percentages of my results.
Bar graph for question 4 of section 2:
Figure 30
In what ways will the economy benefit mostly?
Business: 7 Entertainment: 0 Housing: 8
Travel & tourism: 5
Analysis:
In order to carry out my investigations further, I needed to understand in what ways people thought the economy would benefit most from. We can compare our results of this question to some of our findings from the Stratford officials that we met, we learnt that there will be many houses built, a open stream of travel with the new international station, and the shopping centre which will boast many shops, this shows that all these factors will boost the economy of the area, hence proving my hypothesis two to be correct.
From the bar graph, you can see that many people believe that the economy will benefit from housing mostly, followed by Travel and tourism, Business, and finally entertainment.
Why I chose this type of graph (Presentation):
I chose to use a bar graph to present my data because the results were categorical variables, and using a bar graph would be easy to analyse.
This is the first question for section three of my survey. Section three contains questions based on hypothesis three; this section will contain questions that focus on the environmental impacts of Stratford city and how they will be positive once completed.
Pie chart for question 1 of section 3:
Figure 31
Overall do you believe that the environmental impact of Stratford city will be positive once completed?
Yes: 13
No: 7
Analysis:
This is question 1 for section 3 of my survey; section 3 of my survey is based on hypothesis 3. Hypothesis
From the pie chart above, you can see that a greater number of people believe that the environmental impacts will be positive than negative. I asked this question because I wanted to know what the people thought about my hypothesis, from the results I can clearly say that they agree.
Why I chose this type of graph (Presentation):
I chose to use a Pie chart to represent my data because I wanted to compare the percentages of my results.
Bar graph for question 2 of section 3.
Figure 32
Do you believe that it is important for Stratford City to be environmentally friendly?
Yes: 20
No: 0
Analysis:
I was shocked of the outcome of this question; every person that participated in my survey believed that it was important that Stratford city is environmentally friendly. This shows that people who are from Stratford and who are from neighbouring areas think about such issues. This result will also create a positive sense in terms of the hypothesis when it comes to drawing a conclusion; I know that the developers have stated many ways of how to create a sustainable and environmentally friendly city. This proves that the impacts will be positive once completed hence proving my hypothesis to be correct.
Why I chose this type of graph (Presentation):
I chose to use a bar graph to present my data because the results were categorical variables, and using a bar graph would be easy to analyse.
Pie chart for question 3 of section 3
Figure 33
Do you think that Stratford City being environmentally friendly would encourage you and others to be it too?
Yes: 16
No: 4
Analysis:
No place can be a place without its people, if the people of Stratford city are not environmentally friendly, then there is no point in wasting money and building resources to make the area environmentally friendly, as the people will struggle to maintain it.
For this reason, I created this question in the hope that a high number of people will be affected in a positive way from the developments of Stratford City. My hope was reality; majority of the people I surveyed said that they would be encouraged by the developments, this shows that the majority of the people will be impacted in a positive manor, hence my hypothesis proven.
Why I chose this type of graph (Presentation):
I chose to use a doughnut chart to represent my data because I wanted to find and then compare percentages, alternatively I could have used a bar graph because I had two variables, which I could have compared the frequency, but I thought the doughnut chart was better.
Bar graph for question 4 of section 3:
Figure 34
What type of non-environmentally friendly issues are you concerned about?
Greenhouse Pollution: 6 Congestion: 8
No Green Spaces: 2 Littering: 4
There are many types of non-environmentally friendly issues; in this question I have named the most common. I have included this question to see which one the public are most concerned about,
You can see from the bar graph that the highest frequency of people believed congestion was the biggest concern, followed by greenhouse pollutions, littering and finally, no green spaces. To control congestion in the area, when I asked Adam Brown, he said that the council may provide more public transport in the area, also add the congestion charge scheme, if this does happen then the environmental impacts will be positive, hence proving my hypothesis to be correct.
Why I chose this type of graph (Presentation):
I chose to use a bar chart to represent my data because all my variables were categorical, and if I was to use a bar chart I would find it easier to analyse.
Data analysis for EQI
Play Space
The play space on Leyton Road was very limited; as you can see from figure 35 that I have given it a score of 3, average, there is a small area with a basket ball court for children to play, also a swing. The redevelopments will have many open spaces, and will boast lots of leisure facilities, which will be a positive impact.
Garden Provision
As I scanned and walked through the road, the only living standards were flats which obviously had no gardens, just a small balcony, which some flats had, but others did not, for this reason I gave the garden provision a 1, ’very poor’. On the north side of the site, there will be many houses built which will have gardens; this will be a positive impact.
Figure 35
Parking space for off street parking
I gave this a score of 2, as I walked down the road, I found an off street car park situated on the road, the car park had enough space for roughly about 30 cars.
It is stated on the official Stratford City website that there will be access to 5,000 dedicated parking spaces for shoppers, with additional spaces allocated for residents, office workers and hotel guests. This will boost up the EQI score in the future for Stratford, the use of parking spaces in the shopping centre will probably cost, and therefore bring up the economy of the area as lots of people would come to shop.
Privacy for each family
I gave this a score of 2, poor; this is because the only housing on the road is storey flats, which don’t provide sufficient privacy for each family. Once the regenerations are completed, families will have a higher quality of privacy, in the new houses being built, this is a positive impact.
Freedom from noise
This was definitely 1, all the flats are on the main road, Leyton Rd, the traffic will create a lot of noise along with the sound of machinery and drills coming from the redevelopment site, but this will obviously be gone once the work is over, and there will be less noise, which will have a positive environmental impact.
Freedom from industrial activities
I gave this a score of 1, the first industrial activity is obviously the regeneration site, and then there are many DIY shops on the street, a timber shop, a paint shop. There is also a van rental shop; the noise coming from the site will be over once the developments are complete, if there is a congestion scheme introduced to the area, the traffic levels would also reduce, making the environmental impact positive.
Appearance of the area
I gave this a score of 2, the site although it looks run down, has a few trees which make the road look nice, it did not have nothing extra ordinary such as a statue or ornament to make it look nice, it looked like a normal east end London road. The appearance of the area is proposed to be outstanding, with nicer buildings and open spaces once the work is complete, this would make the environmental impact more positive, and also the overall impact of the developments more positive.
Freedom from traffic
I gave this a score of 1, very poor, I have walked along this street before and it is constantly in presence of traffic. In the Google street view, I can see that there are many cars on the road. Once again if the congestion scheme is introduced, then this would reduce the amount of traffic in the area, making the environmental impact more positive.
Data analysis & presentation for Traffic Survey
Figure 36
I used the results I gained from my traffic survey to create a double bar graph which I could use to analyse the results.
The graph shows that there were more vehicles going into Stratford then out. This tells us a lot of things, one of the things are that there are many people visiting Stratford by the hour; this will increase in the future because of the developments. The increase in visitors will also boost up the economy, because people want to park their car, fill petrol but most importantly, visit the shopping malls; therefore proving my hypothesis two to be correct.
The fact that there are a large number of vehicles entering Stratford is bad because each car is emitting greenhouse gas. In order to make the environment friendlier, the council will have to come up with a strategy to reduce C0² emitions from vehicles, by introducing schemes such as park and ride, or congestion charging.
Why I chose this type of graph (Presentation):
I chose to use a double bar graph to represent my data because it would be easier to analyse. I can easily compare the difference of inbound and outbound vehicle frequencies when the two bars are side by side.
Conclusion
Hypothesis one:
I based each question of section one of my survey on hypothesis one, when I tested these questions on 20 people, 10 males, and 10 females outside the Stratford shopping mall, I gained results which I later plotted on different types of graph. When I analysed the graphs I realised that all the answers to the questions pointed in one direction, my hypothesis according to the results of section one of my survey was correct.
The information that I received from the developers that I met were all positive and I was given the impression that the impacts will be positive.
When I carried out an EQI of an area around the site, I found many bad points, that I knew would improve after the redevelopment was complete, this was a positive impact.
Hypothesis one is correct.
Hypothesis two:
Section two of my survey was about hypothesis two which was about economy. When I asked these questions to the public, I got some mixed responses, but the majority agreed with the hypothesis. When I educated some of the people about the city, and its redevelopment scheme, about how there would be a new shopping centre etc. they knew that there would be an improvement in the economy of the area.
Furthermore, I fixed my view on the hypothesis when I met the developers of the project, when I learnt some of the figures, such as the X amount of houses and new shops; I knew that the economy would rapidly increase.
When I carried out the traffic survey, the results showed me that there were a huge amount of people entering Stratford by the hour, which I knew would increase once the work was over. This would increase the economy.
Hypothesis two is correct.
Hypothesis three:
Section three of my survey was based on hypothesis three which was based on the environmental impact, and how it would be positive once complete. This was proven correct in many ways, when I collected the results on section 3 of the survey and plotted graphs, the responses were positive and most responses were in favour of the hypothesis. When I carried out an EQI of an area near the developments, the total EQI was very low, but I knew this would increase rapidly when the work was complete. I compared the total EQI of Stratford to another case study similar to Stratford, Canary wharf, which was far better than Stratford, but it is proposed that once Stratford city is complete, it will be far better than Canary Wharf as it will boast more facilities like the aquatic centre and the countries largest shopping centre, this shows that the environmental impact of the redevelopment will be positive once complete. The only factor that reduces the environmental impact is the greenhouse gas being emitted from cars entering the city, when I carried out a traffic survey, there was a significant amount of vehicles entering Stratford, this is bound to increase in the future due to the redevelopments, therefore more green house gasses being emitted. This however could be controlled if the council introduce a scheme such as park and ride or congestion charge. When I asked one of the men that I met during my tour of the site about how they will control this, they said that they may introduce a scheme. If this scheme does come into action, then the environmental impacts will be positive.
Hypothesis three is correct.
Limitations, problems and how I overcame them:
When we carried out the survey, we initially planned that we would carry it out inside the mall, however we were not allowed to do this without permission, we resolved to carrying out the survey directly outside the mall instead.
Also we carried out the survey only once on one day, we could have improved our results if we came back on a few other days and carried out the survey, we did not get an opinion from the young generation of Stratford, and this made my results less precise.
When my class mate carried out the traffic survey, she could have done it for a longer period of time, this would have improved the results; another way of improving the results could have been my carrying out the traffic survey from different points, instead of just one.
Another limitation was time, if we had more time, we could have carried out more investigations in order to make our results to the best they can be.
If I was to carry out this investigation, how would I change it to improve it?
There are many things that I could do to improve this investigation; to start with I would carry out the survey again, over a week, and on the weekends so that I can get results from the young generation. I would also carry out the EQI on different roads, and not just limit it to one road.
