What affects the price of second hand cars?
Planning
I will be investigating what affects the price of second-hand cars. To do this I will be choosing 4 cars makes at random and then using different models made by those people as part of my investigation. I will then investigate 5 lines of inquiry, which will be:
- Fuel
- Mileage
- Engine (size in cc)
- Insurance group
- Age
I have chosen these because I think that these factors are what most effect the price of a second hand car.
First I’ll need to write a Hypothesis, which is what I think that I will find out from the investigation. Then I will find out all about the models for each make I choose. Ill need to record the price of them and then record the data for each line of enquiry I have chosen. Then I’ll need to put all this data into tally charts. Then I’ll make graphs out of the tally charts. I’ll be using frequency graphs to look at peak and spread and I’ll use Scatter graphs to find relationships between data. I will analyse these graphs and see how useful they are at answering my question. I will also turn my results into averages and then compare the averages to see which of my lines of enquiry effects the price of a second hand car the most. After I have analysed each graph I will write an evaluation on the analyses to say how I could improve them, what other lines of enquiry I could follow etc. Finally I will write a conclusion to my project.
