# What influences the price of a second hand car.

Maths coursework

Title:

Aim: What influences the price of a second hand car.

I will investigate the following statement:

Do Vauxhalls depreciate faster than Fords?

I will carry out the investigation by seeing which car (out of Vauxhalls and fords) depreciates the fastest, by comparing numerous factors that affect deprecation of cars.

I am to collate data of Vauxhall’s and Fords as evidence and statistics to show the rate of depreciation of a number of cars per yeah.

I intend to investigate the factors that affect the price of a second hand car. During this investigation I am to focus on the age and the percentage depreciation of the car, each year, as I believe age is the main factor to car depreciation.

For my investigation (of car depreciation) I am to get the data from a random database.  Therefore it will be a fair test and the data that I’m to use isn’t related to anything.

## Specifying the problem and plan

Investigation: I shall begin by looking at the data that was given to me. I then decided to place it in a table to make it clearer and to pick out the irrelevant information that I am to need for my investigation.

## Collect process and representation

During my investigation of cars, I will perform the following calculations to help me with my task to see weather my hypothesis was correct.

I will firstly find out the price difference between the price of the car when new to the old price it is to be sold for second hand. I will then compare the difference in price, and see how the age effects this.

I will use the following equations during my enquiry:

Original price – second hand price = Difference

Difference x

Difference x

---------------     = X * 100= % decrease.

Original price

However to make my results and investigation more accurate, I am to work out the percentage of how much the car decreases (depreciates) in value per year.

To work this out I will then divide the overall percentage depreciation by the age of the car.

Original price – second hand price = Difference

Difference x

Difference x

---------------     = X * 100= % decrease.

Original price                     ---------------   ...
