Final Answer :
D
Explanation :
The number of hitting incidents is the dependent variable in this study, as it is what Dr. Santiago is measuring to see if it is affected by the temperature. The control and experimental groups refer to the different conditions that the participants are in (hot or normal classroom temperature), and the independent variable is the variable that is being manipulated (in this case, the room temperature).
