Dr. Reddick is lecturing on various statistical analyses in class. He notes the definition for post-hoc analyses as statistical tests: Select one: a. that examine all of the possible combinations of conditions in a way that statistically accounts for the fact that we did not predict them ahead of time. O b. that determine whether responses from the different conditions are essentially the same or whether the responses from at least one of the conditions differ from the others. O c. that allow a priori decisions to test comparisons between groups predicted ahead of time. O d. in which both variables are categorical and which determine if the distribution of participants across categories is different than expected
