In a classic study of the effect of memory on caffeine, Loke (1988) studied the effect of caffeine on the serial position effect. In memory tests, the serial position effect refers to the observation that memory for items at the beginning and end of a list are remembered better than items in the middle of a list. Loke observed an interaction between caffeine dose (low, moderate, and high) and position (1st, 2nd, 3rd, and 4th block) in a list of recalled items. A pattern of results like those reported by the researcher is described in the table below.

Complete the following ANOVA table. Use an ANOVA with α  = .05 to evaluate the data. Describe the outcome of the study.
