ooking at the dependent variable (DV) in your graph, identify at least one research question that requires explanation. The question can be about why there is so much variation in the DV or so little variation in the DV across units/groups. Or it might be why one of the "units" or groups on the graph have very different values of the DV than other units/groups. Identify why you might have expected the DV to show LESS variation across units. Then identify why you might have expected the DV to show MORE variation across units
