Alice's study examined the benefits of early morning exercise on young children's attention during circle time. She had two groups of students, one who came to circle time first and then had recess and a second group that had recess before circle time. She is comparing the groups' attention based upon a frequency of off-task behaviors by group at circle. The likely measure of Alice's dependent variable is

The dependent variable in Alice's study is the frequency of off-task behavior by group at circle time. The most appropriate measure of central tendency for this variable would be the mean, as it would give an average score for each group. The range measures the spread of the data and is not an appropriate measure of central tendency. The mode and median are also options for measuring central tendency, but the mean is most commonly used and would provide the most accurate reflection of the average off-task behavior in each group.
