Problem: A developmental psychologist is looking into the effects of play group size on empathy and whether this differs by age. She has two age groups - four year olds and eight year olds. Each of those age groups is split into three separate groups for an entire semester during structured free time: play alone (n = 8 per age group), dyads (n = 8 per age group), or groups of 4 (n = 8 per age group). At the end of the semester, empathy is measured using the Young Children's Empathy Measure during the parent-teacher conference (Poresky, 1990), which uses an accuracy scale of 0 - 4, with higher scores indicating more cognitive and affective empathy.
