It looks to me like your independent variable is the temperature as measured by a thermometer, the dependent variable is the estimated temperature based on cricket chirps. Crickets, like all living things, have many chemical reactions going on inside their bodies, such as reactions that allow muscles to contract to produce chirping. In all cases, T is the temperature and N is the number of chirps per minute. Let Them Chill Out. An official website of the United States government. As the temperature rises, it becomes easier to reach a certain activation energy, thereby allowing chemical reactions, such as the ones that allow a cricket to chirp, to occur more rapidly.
