A student investigated whether ants dig more tunnels in the light or in the dark. She thought that ants used the filtered light that penetrated the upper layers of earth and would dig more tunnels during the daytime. Ten ant colonies were set up in commercial ant farms with the same number and type of ants per ant farm. The same amount of food was given to each colony, and the colonies were in the same temperature. Five of the colonies were exposed to normal room light and five colonies were covered with black construction paper so they did not receive any light. Every other day for three weeks the length of the tunnels was measured in millimeters using a string and a ruler. Averages for the light and dark groups for each measured were then computed. The averages are listed in the following chart:
