They may order the categorical values by frequency and look for the category with the middle Example.

The number of voters sampled from the first state (n1) = , and the number of voters sampled from the second state (n2) = Find the mean of the difference in sample proportions: E(p1 - p2) = P1 - P2 = - = Find the standard deviation of the difference.
