Christopher has heard that the chirping of crickets varies with air temperature. he performs an experiment in which he counts the number of times crickets chirp in 30 seconds at different temperatures. his data are shown in the table below. what is the independent variable in this experiment?

Temperature is the independent variable in the experiment.

Explanation:

An independent variable can be described as a variable which is being changed or varied in an experiment. Whereas, dependent variable can be describes as the variable that gets effected or responds to the changes caused by the independent variable.

In this experiment, temperature is the independent variable as we are changing or varying the temperature. The number of chirps is the dependent variable as they are being affected by the change in temperature.
