PLAN

For my coursework I was given a database on cars, which gave information on various properties of second hand cars. Then I had to use the data to find out what factors mainly affected the price of the second hand cars.

I was given a list of total 100-second handcars. I predicted that 100 cars would be too much to handle at one time and it would be too difficult to have perfect results.

So, I’ve decided to go on with only 30 cars. This would help me to get detailed results. Now, I would divide these 30 cars into 15 Vauxhall and 15 ford cars. I preferred 2 different makes of cars so that I can compare the results I get from both makes and get more detailed results.

I am going to find out how each of these issues affects the price of a second hand car.

•   Age
•   Engine
•   Mileage
•   Insurance

Now I would compare each of these with the second hand cars and would do this with both the makes of the cars (Vauxhall & Ford). After comparing each issue with the second hand price, I would be

Conclusion

I think that I would have also compared the colour of the car. I think that the colour of the car also does affect very nicely on the price of the second hand car. Also, on the make of the car. Although I’ve not compared both the colour & the make of the car but I’ve given some examples in between.

While comparing both the Ford cars as well as Vauxhall cars I found out that the Ford cars depreciates its price very quickly as compared to the Vauxhall cars. I could see the major difference between both the cars when I was finding out the depreciation rate of both the makes. If I wanted to buy a second hand car then I would’ve definitely gone for a Vauxhall car.

The predictions that I made in the beginning matched completely with each and every graph while I was comparing both the cars.

In the end I decided to make graphs on cumulative frequency and add box and whiskers that helped me getting better results.
