Testing the Hypothesis: More Insects Near the Cafeteria?

Dependent Variable: Number of Insects Trapped

In an experiment, the dependent variable is the one that is measured or observed as the outcome. It is the variable that is expected to change in response to the manipulation of the independent variable. In this case, the researchers are interested in studying the number of insects trapped near different locations (cafeteria, gym, library) to test their hypothesis.

By setting up five pit traps at each location and leaving them in place for three days, the researchers can collect data on the number of insects trapped. This data will allow them to compare the number of insects trapped near the cafeteria with those trapped near the gym or library. The dependent variable, in this case, is crucial for determining whether there is a significant difference in the insect population near these different locations.

It is important to note that the dependent variable is also known as the responding variable because it responds to changes in the independent variable. In this experiment, the location of the traps is the independent variable as it is being manipulated to observe its effect on the number of insects trapped. By focusing on the number of insects trapped as the dependent variable, the researchers can draw conclusions about the distribution of insects near the cafeteria compared to the gym or library.
