The dependent variable is the variable that is being tested or measured, in this case, it is the rats' learning performance, as this is the variable that is being compared between the two groups in different temperature conditions. The experimenter, temperature of the room, and size of the room are not dependent variables, as they are not being tested or compared in this experiment, but rather are independent or control variables.
