Investigating How the Prices of Used Cars Vary From New Cars

PLAN

====

I am going to investigate how the prices of used cars vary from new

cars. I am going to sample all the cars that are two years of age and

under and compare it with cars that are in the range of five to eight

years old. I am going to compare two different cars makes with each

other and I am also going to sample out all of the cars with the

mileage of 70,000 and less and compare it the price of the cars with

the mileage of more than 70,000.

I will plot the prices of cars on different graphs, draw a line of

best fit and compare it with the others. So I will have three

different types of graphs that are going to be age against price, make

against the price and mileage against the price.

I collected the following data for my coursework:
