2. Crickets and Temperature
One classic application of correlation involves the association between temperature and the number of times a cricket chirps in a minute. Listed below are the numbers of chirps in 1 min and the corresponding temperatures in Fahrenheit (based on data from The Song of Insects by George W. Pierce, Harvard University Press. Is there a linear correlation between the number of chirps in 1 min and the temperature?
Chirps in 1 min 882 1188 1104 864 1200 1032 960 900
Temperature (F) 69.7 93.3 84.3 76.3 88.6 82.6 71.6 79.6
