Results Results of this experiment are shown on the attached page. Conclusion A controlled experiment is one in which all the variables except one are held constant. The single variable that is manipulated (the independent variable) is done so in a controlled way, in order to observe and measure the effects on the dependent variable. In this experiment, the rate of chirping increased with temperature. The other variables (wind speed, number of crickets, humidity and atmospheric pressure) did not impact the number of cricket chirps.

The rate stayed at 148 beats per minute in these tests.We met our purpose, hut our hypothesis was not supported. We needed at least six data points in order to make a reasonable conclusion. If you only pick larger values, you don’t have information about what happens on the other side you need to support your conclusion.
