# Investigate what affects the price of a used car.

Extracts from this document...

Introduction

## Introduction

For my maths coursework, I have been asked to investigate what affects the price of a used car. I have been given information on 100 cars. On each car I have details of its

• Make (e.g. Ford)
• Model (e.g. Fiesta)
• Colour
• Price when new
• Current price
• Age
• Colour
• Engine
• Petrol Type
• MPG
• Mileage
• History
• Service?
• Number of owners
• Length of MOT
• Tax (months)
• Insurance group
• Doors
• Style
• Central Locking
• Seats
• Gearbox
• Air conditioning?
• Airbags?

In the information there are 26 different brands of car.

## The value of a car decreases exponentially with age

By decreasing exponentially I mean that in a graph of a certain type of car, with age along one axis and its value along the other, a downward curve would be seen, for example:

## Plan

The factor that I am first going to investigate, as I believe it to be the most important factor affecting the selling price of the car, is the age. As there is a lot of

Conclusion

A scatter diagram showing the Used Price of the car against its Mileage:

 Used Car Price (£) Mileage 4295 29000 4700 34000 3200 27000 2975 96000 3400 66000 6995 35000 8800 7200 8250 34000 13500 6500 2975 96000 7550 5000 3495 43000 7995 30000 3685 64000 4976 21000 3495 55000 1664 37000 4693 50000 6995 63000 1995 5200 3995 57000 3191 43000 2995 64000 4995 52000 7999 7000 7999 20000 6595 30000 6999 30000 7499 27000 6499 49000 4995 24000 3795 51000 2495 33000 895 43000 1000 75000 400 None shown 3695 49000 1700 55000 1050 90000 1495 74000 1995 60000 2300 64000 2900 58000

I can see from this graph that there is very little correlation between mileage and age.  Therefore this is not the most prominent factor affecting the price of a second hand vehicle.

Conclusion.

In conclusion, the price greatly drops, in relation to the age of the car, the older the car, the cheaper it is to buy. The price is also determined by the mileage, but as greatly as by the age. All cars show this data, but it is more prominent in some than others. The price depreciates quite dramatically for the first three years, and then gets less and less as it continues to drop in value. For more proof of this see the graphs and tables I have made above.

The range and decile range for the price and mileage are closer together than the interquartile range so I think the interquartile range is leaving too much data out.
