According to the Farmer's Almanac, the frequency of cricket chirps varies according to the ambient temperature. As a result, by counting the number of chirps and dividing by the time period, the temperature can be predicted using a linear equation. The dataset in the second sheet of the spreadsheet linked above, provides 15 observations of the number of cricket chirps per minute and the corresponding temperature in degrees F.

The equation for the least squares regression line is ^y = 3.291x + 25.232
