Reporting Results in Factorial Between-Subjects ANOVA (3 of 4)

---

An Age (2) x Type of stimuli (2) analysis of variance was used to test differences between means for significance. Figure 1 shows the mean percent correct on the recognition test as a function of age and type of stimuli. An inspection of figure 1 reveals that the effect of age was much larger for the word stimuli than it was for the pictorial stimuli. The difference was reflected in a significant Age x Type of stimuli interaction, F(1,28) = 6.37, p = 0.018. It is also evident from figure 1 that, overall, 12-year olds performed better than 8-year olds, F(1,28) = 9.35, p < 0.01.
