Question

A scientist is studying the effect of temperature on a certain species of bacteria. To do so, he measures the metabolic rate of different bacteria colonies from this species 20 times over a wide range of different temperatures that he sets in his lab. He then computes the correlation of metabolic rate and temperature for this species and is surprised to find a very small correlation of -0.04, very close to 0. He concludes that temperature has essentially no effect on metabolism for this species. Do you agree with his analysis? Why or why not?

Explanation / Answer

I agree with his analysis. This conclusion about the correlation is right.
