                      MATHS STATISTICS COURSEWORK

For my maths coursework I will be conducting an investigation into statistics. I had a choice for this coursework of both statistics on year 10 to 11 school children, and facts about them and also their likes in terms of sport and subjects at school. I chose not to do this project on that information; instead I chose data on 100 different cars, the reason for this is that I like cars more and may perhaps pursue it as a career. I did not want to do a project on data that I have no interest in.

The 100 different cars have data under the following headings, Car number in order from 1 to 100, the make of the car, the price when new of the car, the current second hand price, the age of the car, the colour of the car, engine size e.g. 2 litres, the type of fuel the car uses e.g.

Middle

There are 23 different headings under which data has been entered, and there are 100 cars in this survey. Using this information I can make an equation

100 (different cars) x 23 (different headings) = 2,300 datum points.  

This means that there are 2,300 different pieces of data in the survey.

For my coursework I will be hopefully conducting a total of 3 different investigations into this survey, though this may change to 2 or 4. My aim is to look for a correlation in the separate investigations and perhaps if I can draw any conclusions or maybe find a formula or prediction for a particular investigation that will work for all or most cars. E.g. if from mileage, price when new and age I can calculate the current second hand price.

My investigation will be:

The frequency of mileage in my sample, if there is a relationship between the second hand price

Conclusion

MY Predictions

These predictions relate to the numbered investigations.

  1. I think that the more mileage, more owners, and older the car, the less it will be able to sell. The percentage loss in price of each car will be higher relating to the higher the three factors are (mileage, age, owners). I hope to draw up a formula from this, to calculate the re-sale price of cars given the three factors. I feel there will be a strong relationship between the percentage loss of a car and its Age, but perhaps a weaker or no correlation between the second hand price and age of the cars.

When comparing cars, I will have to insure my investigating is fair, by only sampling cars that are exactly the same or have a few minor differences, I cannot compare the re-sale price of a Ford and a Bentley, as the Bentley will be a higher price if though it is older.

  2. Used second hand cars

    This is obviously caused by their price when new. The graph also seems to produce a poor correlation due to the same reason. This graph also seems to produce the same result as the graph obtains through pilot survey. There is a stronger negative correlation between the age and second-hand price when considered together.

  1. Factors affecting price of Used Car

    This is because as the price drops, the mileage increases. And also showing a negative correlation as the price drops faster when the car is younger than the older and the price will never reach a negative price. It might gradually become cheaper and cheaper but it will not reach a negative value.
