Statistics on car prices

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.

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

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.

    The Scatter Graph shows that there is weak negative correlation between price and age of the used cars. This is because as the age increase the price decreases. Analysis My data suggests that my hypothesis (the older a used car is the lower the price) was correct to some extent.

    Saloons are very modern, attractive cars compared to the hatchbacks and others, therefore I think that the depreciation values for Saloons will be generally lower than for the other cars. To prove this I will list all the cars in the database under the headings of Saloons, Hatchbacks and others.
