The dependent variable in this experiment would be the frequency with which students ask questions, as that is the behavior being measured and compared between different chair arrangements. Choices A and B are measures of class demographics and do not directly relate to the research question, while choice C is the independent variable being manipulated, not the dependent variable being measured.
