"The price of a silver used car will be higher then that of red and blue used cars"

Introduction

Hypothesis 1

“The price of a silver used car will be higher then that of red and blue used cars”

The Price of a used car is affected by the colour. I think that the colour of the car will distinguish different sets of prices. For example, red car prices may be higher than green cars because they are more common. The colours I will be comparing are blue, red and silver, as I feel that they are the most common car colours. I think that silver cars will have the highest range of car prices, because after researching in the ‘Auto Trader’ section of the local paper, I have discovered silver is the most common colour of cars, followed by blue.

Conclusion

Conclusion for Hypothesis 1

Relating back to the beginning of this investigation, I have found that my hypothesis “The price of a silver used car will be higher then that of red and blue used cars” is correct. After investigating this by using scatter graphs and box plots I found that the results not only supported this, but strongly supported it. I now know that colour is a very important factor in the sale of a used car, and silver is the most common and expensive car colour above red and blue.
