Data Handling: Used car prices

Introduction

The aim of the coursework is to find which factors will influence the price of a second hand car and in what way. I have been given a large list of cars from my teacher with many different factors about them. I believe that the price second hand cars are sold at is dependant upon several factors, certain factors will have a much larger effect on the price than others. I my investigation I am going to chose the 3 most popular manufacturers of cars from a tally chart of all of the cars because the thing that people look at first when they are buying a car is the make and I believe this is will affect the second hand price the most. Certain cars have a very good reputation of being reliable while others are not. Also some cars have a higher social status than others for example people would prefer a Porsche over a Ford. I will also investigate the price depreciation, age and mileage that has been done

 So the factors that I will investigate in my coursework are

  • Make or manufacturer
  • Mileage
  • Age

I will not investigate any of the other factors because I think that they will not have a large impact on the second hand price of a car for example colour is not very important to the price of the car because cars are made in lots of different colours and sold at the same price, the only reason the colour would affect the price of a car would be if the buyer preferred a certain colour of car. Another factor that is not very important is the amount of seats the car has, most cars have 5 seats and this is only important is people are looking to buy large people carriers but even then it would not affect the price of the car profoundly

Below is a tally hart which shows the totals of all of the different cars that were given to us

From the tally chart I am going to pick the three most popular cars makes to conduct my investigation on. These will be

  • Ford
  • Vauxhall
  • Rover

These cars were picked because they have the largest amount of information to plot graphs with and there is a wider range of information to conduct the investigation with. For example if I chose to investigate Rolls Royce it would not be effective at all ...
