Investigation of factors that effect the price of a car
Introduction:
For this investigation I will be using the data to investigate what factors influence the price of a second handed car. To do this first I will specify clearly what I am going to do and why I am going to carry out the investigation this way. Then I will collate the data that I need and represent it in a way that helps me to develop my investigation. Finally I will interpret my results and draw conclusions from them. I’ll be using tally, Bar charts, cumulative frequencies, frequency charts, scatter graphs and Pie charts.
Planning:
First I shall provide the data all the cars that will show Price Vs Mileage, Price Vs Age, car ownership and number of cars per model. After that I will pick out the top 3 cars which reappear the most in the charts and graphs. After that I will examine the Price Vs Mileage, Price Vs Age of those 3 selected cars. I will then see what factors or what qualities do these cars have which are affecting there price and popularity for e.g. Mercedes may not be owned by that many people because it is a prestige car and has all the qualities, it still holds its price. The reason for car ownership could be that the Mercedes might not be affordable because it is too expensive for some people or isn’t affordable. After doing so and once I have examined the factors affecting each of those cars than I will do frequency charts and Cumulative Frequency graphs on age, mileage and price for each one of those 3 selected cars. In order to show what and how some of the factors are effecting the car, I will include some writing under the graphs and charts to make them clear and easier to understand
Price, Age and Mileage: All Cars
Price Vs Age:
Ford
According to this Scatter Graph, as the car gets older in age the more the car keeps on dropping its value. This means the higher the mileage, the larger the price of the car decreases, but at some point most of the cars have a high age yet the price is also high the reason for this could be that safety wise the car has air bags which the owner or the buyer of the car may consider, the car has along MOT which will save the owner money, there could be a possibility that the facilities of the cars are up to standards such as it has had services or has air conditioning. The same reasons apply to the 8 cars shown above the trend line.
Rover
