DATA HANDLING

MATHS COURSEWORK

MR UDDIN

Introduction

In this investigation I would looking at what factors affect the price of a second hand car. The things that I think that affect the price of a second hand car are:

Mileage       (The car might be warn out by all the journeys that It went    

                     through)

Engine Size (How fast a car travels and the size of the engine)

I have decided to follow the following line of enquiry, the difference between the mileage and the price and how it affects it.

My Hypothesis is

The higher the mileage the higher the price drops

I would look at the price drop by using the following

%drop in price = Price when new- 2nd hand price image00.png

                            Price when new

  1. First I am going to randomly select 30 cars from the data sheet

I am now going to explain how I had worked out % price drop in price

The formula is

%Price Drop = Price When New – 2nd Hand Price x 100

image01.png

                                          Price When New

Now I am going to choose 1 car from the table and show how I done it

The formula is

% Price Drop in = Price When New- 2nd Hand Price x 100

image01.png

                                                Price When New

I have selected a car from the table to show how I have worked out the % price drop

% Price Drop in = 8601 - 3995 x 100

image02.png

                                          8601

=0.53x100

=53

Now I am going to present my data using a scatter graph. The scatter graph would show if the factors would have a correct data or not.

Looking at my graph I can see it is a positive correlation. This correlation is a week correlation, it is scatter around.

  1. Factors affecting price of Used Car

    This graph shows a very weak negative correlation. This is indicated by the gradient being -29.74. It has the lowest gradient and also there seems to be a contradiction between the others and this one. This negative gradient tells us that as the engine size increases, the price decreases which is incorrect.

  1. Data Handling Coursework

    I will go about this by first tabulating my sample, then the difference between the brand new cars and the second hand cars. I will show this by drawing a scatter graph and seeing if there is any difference in the prices.

  2. Mathematics course work

    Now I will show a line graph to show the trends of the 5 cars. By looking at the line graph I can say that it has a weak negative correlation because when the age is low (2) the price is high (�10995) and when the age is high (11)
