Quizplus · Accepted Answer

The dependent variable in this experiment is the rating of happiness, as it is what is being measured and expected to potentially change due to the independent variable (temperature of the booths). The other options (number of participants and elapsed time) are not relevant to the hypothesis being tested. While temperature of the booths is the independent variable, it is not the dependent variable being measured.
