Quizplus · Accepted Answer

The dependent variable in this experiment is the reading skills level, which is being measured at the beginning and end of the experiment to determine the effect of peer tutoring. The independent variable is whether the group receives peer tutoring or not. The number of children in each group is not a variable being measured or manipulated, so it is not the dependent variable.
