Note: Dolbear's law is best at estimating temperature when tree cricket chirps are used, when the temperature is between 55 and 100 degrees Fahrenheit, and on summer evenings when crickets are best heard. I picked 48 and got 81 as my y value (48, 81), If we insert those numbers in the formula using my example, we now have: m = (81 - 76) / (41 -48), Now that we have m, we can choose any value on the line, say (x, Plugging in m and b my cricket equation is: y = .71 * x + 46.7 or Current temperature (F) = .71 * cricket chirps in 15 seconds + 46.7. A) Crickets are inactive in October. Do you love to hear the pulsing chirp of crickets as you fall asleep?
