2. ## Statistic coursework-what has the most influence on the price of a second hand car?

Moreover, I assume all the secondhand prices of cars are in 2005 because the database provided by the exam board did not state which year the secondhand price belongs to. Car no. Make mileage Year Cost when new (GBP) Secondhand price (GBP) 1 Mercedes 12000 2000 26040 11395 2 Mercedes 20000 2002 35025 25995 3 Mercedes 9000 2000 35025 19955 4 Mercedes 47000 1998 15640 4635 5 Mercedes 73000 2002 32867 24435 6 Mercedes 49000 2000 24590 13570 7 Mercedes 12000 1996 23805 3885 8 Mercedes 90000 1999 39040 12800 9 Mercedes 61000 2000 24590 13455 10 Mercedes 58000 2001

3. ## Maths - statistical driving test

Investigations From the previous breakdown I have decided on three areas of investigation. Each investigation will start with a hypothesis, which I will prove or disprove through the process of in-depth data analysis. Hypothesis one :- The more lessons a student takes the less mistakes they should make. Hypothesis two :- The more lessons a student takes the less mistakes they will make depending on their instructor. This means that some instructors are better than others. Hypothesis three :- On average males make less mistakes than females.

4. ## Maths Coursework:Used Cars

I am using this method because it is fair and unbiased. Using this pie chart I have decided that the four most popular cars are Vauxhall, fiat, ford and rover. This is because these cars are most common cars in the population and the other cars have single models so the results will not be reliable. Also the size of the database is very small and if I could do the survey I would choose a much bigger database. Stratified sampling I will use the four most popular cars in order to carry out the stratified sampling.

5. ## Theory of Whether The Age of a Car Is Directly Proportional To It's Depreciation

This scatter diagram displays the information on the Ford Cars table. This scatter diagram displays the information on the Fiat Cars table. Both scatter diagrams above show a positive correlation and this means that as the age of a car increases the cars depreciation or decline in price increases. However, some of the cars do not follow the same pattern, for example, a one-year-old Ford car lost about 50% of its value whereas the three-year-old Ford car only lost 38%.

6. ## I will research the cars by putting the data I have been given into statistical charts, graphs and tables to analyse them. I will use a scatter graph to firstly look at how age affects all cars depreciation

From the line I can also create a box plot and read the lower and upper quartiles, the inter quartile range, the median and the range. On this graph the lower quartile would show that a car loses a quarter of its value in however many years, the upper would show that the car depreciates three quarters in however many years and the median, half in however many years. The inter quartile range would show the distribution of the central fifty percent of the cars.

7. ## Data Handling Coursework

if it is new or second hand, the engine size, the mileage and finally the make. My first table will show all the factors that I think that will affect the price of the cars. The reason why I have chosen the cars that I have is mainly because they are the ones with the same makes i.e. the ones that there are a lot of from the same make. I have also chosen exclusive cars as I hope this will make the range of my investigation wider. Plan: I plan to investigate the following factors, the price difference and the percentage depreciation of a brand new car compared to a second hand car.

8. ## in this investigation I will examine what factors affect how a second hand car is priced

After finding my sampling cars I shall check and show the price depreciation of each of the cars in the selection. I will do this by using the equation: Following from the price depreciation I will find out the mean price and the mean age and mean mileage. After doing this I shall do scatter graphs for each of the factors I have chosen to investigate against the price of a second hand car. With doing that I shall do a line of best fit and then find out the equation for the line of best fit and then try and predict with a certain price does the factor affect it.

9. ## Henry Ford

Made by Benz, this car was three-wheeled, very uncomfortable and extremely slow, going approximately 10 miles per hour. From that date forward, Henry Ford found out what he was destined to do, build an incredible car. Before Henry was going to build any car, he had to first get some money so he decided to work for Westinghouse Steam Engines in southern Michigan. April 11, 1888, was a great day for Henry, because he married Clara J. Bryant. Mr.

10. ## Investigate the affect that age has on a car in terms of performance and structural integrity

After each of the diagram I would explain how I did the diagram. At the end of the coursework I would be doing a conclusion explaining what has happened and why. I have hosen 100 cars randomly fro the database instead of 1402 because I think it would cause inaccurate results. When I say randomly I mean I the cars that would give better results. I am going to calculate the number of each type of car according to its age and mileage. I would provide my entire hypothesis to get more accurate results and also to include my prediction.

12. ## HEFP STATISTICS ASSIGNMENT REPORT

In this case, I decide to select 30 samples. Finally, use the calculation to randomly choose certain samples from a variety of data. In calculation, press "mode" and then chose fix. After that use the number of cars to be chose from multiple Ran# and add 1, which will give you the representative samples selected by calculation. The numbers of the cars we choose from each group are calculated as showed below: 32/100 ?30 = 10, so 10 data should be chose from group of small engine cars . 61/100?30 = 18, so 18 cars out of 100 cars of medium engine cars will be chose from. 7/100 ?

13. ## I have been given instructions to collect data for my GCSE statistics coursework and then to represent them by interpreting them using graphs and attributes, which I think influence the prices of a second hand car.

Collecting data Two types of data used can be Primary data and secondary data. Primary data is data that is collected by or for the person who is going to use it. Secondary data is data that is not collected by the person who uses it. Data can be collected using an experiment of survey. In a statistical experiment, one of the variables is controlled while the other is observed. The controlled variable is called the explanatory or independent variables The effect being observed is called response of dependent data.

14. ## The Ford motor company and the Pinto Gas Tank: A case study in corporate ethics

APPROACH The three principle elements of social responsibility (externally mandated actions, market actions and voluntary actions) that played a role in the decisions made by management at Ford will be investigated. In addition, a review of some of the principles of ethical conduct: might-equals-right, conventionalist, intuition, proportionality and utilitarian ethic will be reviewed with regard to the actions taken by the Ford Motor Company involving the Pinto. LITERATURE The original documents used to gather information for the development of this paper include (1) books, (2) court cases and (3) periodicals. Reference to these and other sources can be found as citations in the endnotes. INTRODUCTION The Ford Pinto was introduced for sale to Americans in 1970.

show us the anomalies and why they are anomalous and with this data we can see how we can improve our data collection. I am going to first use a scatter graph of new price against old price. I will use all data given to us by the board with a couple of exclusions here and there. I am going to exclude all luxury cars and classic cars. I am also going to exclude all cars with a new price above �20'000 as the factors that affect their price depreciation will change for a more expensive car.

20. ## What factors affect the prices of used cars?

There are some colours that most people would like or wouldn't mind (e.g. silver), but on the other hand, there are some colours that only a very small proportion of the population would like (e.g. pink). Only a very small amount of people would be willing to buy a pink car forcing the seller of the pink car to reduce the car's price so as to increase sales. An article in the Mirror on the 12th of March stated that silver cars hold their value more than cars that are any other colour only because it is the most desirable of colours.

21. ## In the maths coursework we have been set, we have been asked to use information provided to investigate what influence the price of a second hand car.

I will use graphs such as bar graphs, pie charts and even scatter diagram to present my data. I will also use methods such as finding the average of the prices and ages of the cars and the cumulative frequency of the data that I will collect from the database on the cars. In the coursework I have to use the data which is related to one another, and when the data is compared, the outcome will show how the price varies due to the different factors.

22. ## This piece of coursework is designed to test the use and interpretation of statistics in relation to used car prices.

I predict that the mileage of a car will make a considerable difference to the price of a car, as the higher the mileage, the less value the car will have. 4. The number of owners that a car has had may also cause a decrease in value as the condition of the car may vary. 5. Finally, I predict that the extra features of a car, e.g., air conditioning, central locking, etc. will also boost the price of a car.

at the very beginning or at the end. I will also use the exact same cars for each three hypotheses. Hypothesis 1 - The price of second hand cars will decrease with age. Hypothesis 2 - The price of second hand cars will increase with engine size. Hypothesis 3 - The price of second hand cars will decrease with the amount of mileage it has done. I will compare the two pieces of data in the hypotheses to either prove or disprove the hypotheses. I will use standard deviation, graphs and other equations to show the methodology and findings of the hypotheses.

26. ## The aim of our coursework is to investigate the effect of different variables on the price of a second hand car.

3. I predict that the price of a used car is dependant on mileage. This is because as the mileage of a car increases, the car becomes less desirable. Also as the mileage increases so does that age of the car. This increases depreciation and so I expect there to be a positive correlation between mileage and percentage decrease in price. In order to prove or disprove the above hypotheses I will be using a stratified random sample as shown below. This sample was created by choosing a sample size of 25, as it is divisible by 100.
