Dr. Wawanosh is investigating the effect of high room temperature on aggressive behaviour in preschoolers. Half of the children are in a classroom where the temperature is a warm 31°C and half are in a classroom where the temperature is a normal 25°C. Dr. Wawanosh measures the number of hitting incidents that occur in each classroom. In this study, which group is in the classroom with the normal temperature?

The control group is the group that is not exposed to the independent variable (in this case, a high room temperature). It is used as a basis of comparison to determine if any effects observed in the experimental group are actually due to the independent variable or to other factors. Therefore, in this study, the group in the classroom with the normal temperature (25°C) is the control group.
