Introduction:
- We as a group decided who should be within our group by thinking who the hardest workers are and who would actually want to do the work. The three of us (Barry Boston, James Bolton and Minesh Patel) are also friends so we knew that we would get along with each other. We thought this would be the perfect combination; with hard work and people who can get along and understand each other.
- We started working on the coursework immediately. We all started off by creating our questionnaires and collecting our data. Then we created our results tables.
- I chose all of the music that we used in our questionnaire by researching all of the most popular styles of music and then picking the most general styles to be entered within the questionnaire.
Method:
- I am going to collect my data by asking a number of random people from each year and recording their data within tables, after this I will put the results into graphs.
- I am going to decide on what questions to ask by using questions that are closed, not biased and give me the results I need.
- To stratified sample, I will find the total of each year and divide them by the total of the whole school. After I will times this answer by 5% of the total of the school= around 30 students.
Selection and Collection of data:
- I decided to collect primary data and I thought this would be an easier way to work out whether or not my hypothesis was correct.
- The data is representative of the population of the sample that I used. In some references it may be biased because it doesn’t use the opinions of the total school population.
1st Pre-test questionnaire:
Why was each question biased?
- ------
- ------
- Overlapping answers.
- Question is too open.
- Overlapping answers.
- The question is biased.
- It skips amounts.
- Question is too open.
I looked at all of the flaws and created a corrected questionnaire, which I used as my final questionnaire.
The stratified methods I used:
5%=30 students
Year 7= 119/588*30= 7
Year 8= 121/588*30= 7
All Figures are rounded.………..
Year 9= 136/588*30= 7
Year 10= 106/588*30= 6
Year 11= 106/588*30= 6
Total = 33 students.
The sampling method I used was stratified sampling because I thought it would be more accurate. In stratified sampling a population may contain separate groups of strata. Each group needs to be fairly represented in the sample. The number from each group is proportional to the group size. The selection is then made at random from each group.
Presentation Of Data:
I have used these methods of presenting data because the tables may allow you to study the different types of answers given by each candidate and the graphs can show the variations between the answers given by the candidates.
Interpretations and conclusions:
I have found that my hypothesis was almost correct by in some places it wasn’t like with the new metal hypothesis. As you can see from the diagrams, some people do still listen to this style of music and so it is also true that new metal/grunge is quite popular in school.
