Australian Statistics Assignment 2012

1. Australian Statistics Assignment 2012 “If you measure the temperature of a car’s roof, will the colour of the car affect the results?” ByKeelanTaylor,KhloeJohnson&CallanKneale

2. Introduction The purpose of our experiment is to determine whether the temperature of a car is affected by it’s colour. To ensure our test is fair we composed this question to base our experiment on: “If you measure the temperature of a car’s roof, will the colour of the car affect the results?”

3. Hypothesis Our expectation was that we would find that black cars have the hottest temperature and white cars will have the coldest temperature. This is our assumption because black absorbs sunlight whilst white deflects it.

4. Data We measured the temperature of each car’s roof, measuring only black, white, blue and silver cars. For each colour we measured the temperature of the roof of 10 cars. We collected our data from the staff car park at Australind Senior High School, using a laser temperature camera. All of our data was collected on the same day so our results were not affected by the temperature of the day.

5. Our Findings

7. Analysis From the data we collected we were able to identify that cars which were black had the hottest temperature with an average temperature of 49.55°C. The car with the coldest temperature was the white cars with an average temperature of 31.30°C.

8. Conclusion After conducting a fair experiment we were able to determine that the colour of a car does affect its temperature. Therefore with climate change occurring maybe in the future all cars will be white.
