Question 1

A researcher notes that there is a positive correlation between the temperature on a summer day and the number of bees that he can count in his garden over a 5-minute time span.
a. Describe what the researcher means by a positive correlation.
b. If the researcher calculates the correlation coefficient using degrees Fahrenheit instead of Celsius, will the value be different?

Question 2

One of your classmates is working on a science project for a unit on weather. She tracks the temperature one day, beginning at sunrise and finishing at sunset. Given that you are know for being the stats expert, she asks you about calculating the correlation for her data. What is the best advice you could give her?

Answer 1

a. As the number of degrees increases, the number of bees increases in a linear manner.
b. No. A change of units will not change the correlation.

Answer 2

She needs to graph her data first and see if it is a linear pattern. Which it almost certainly is not. It will go up and then come back down, probably in a curve. So correlation is not going to be appropriate.
