Create a x-y line graph of the temperature values for each day on the same graph. Refer to Technical Hints to see how to create a x-y line graph.
Use your graph to complete the following on paper:
Review your predictions about the warmest and coldest time of the day. How did the data compare to the predictions? What is the general pattern in temperature changes each day?
How much does the temperature vary each day? How does the high or low vary each day? What is the high and low temperature of both days? How did weather conditions affect the highs and lows?
The mean (or average) daily temperature is the sum of all of the temperatures taken during one day divided by 24 (the number of temperature readings taken over the day). How did the observable weather conditions relate to the mean temperature values? Refer to Technical Hints to see how to calculate the mean temperature. What is the mean temperature each day? How much does the mean vary each day? Suggest a method to calculate the mean temperature over both days. What is that temperature?
Compare your line graph to other groups that placed their temperature probe at different locations. Explain any difference in the data.
