Module 3 – Two-way ANOVA
In this assignment, a two-way ANOVA test was conducted to study the effects of the perceived importance of a task and interference/distraction on memory. The test was conducted using SPSS.
The two-way ANOVA results showed there was a significant main effect of interference, F (1,16) = 36.779, p < .001, ηp2 = .697, such that interference (M = 59.30, SD = 5.36) had a lower memory score than no interference (M = 80.40, SD = 15.87). This indicates the effect of interference on lowering the memory of the topic being addressed to the participant. There was also a significant main effect of importance, F (1,16) = 69.955, p < .001, ηp2 = .814, such that not important (M = 55.30, SD = 14.41) had a lower memory score than highly important (M = 84.40, SD = 12.14). This indicates the effect of importance on the memory of the topic being addressed to the participant. The interaction effect was not significant F (1,16) = .001, p = .977, ηp2 = .000, indicating there was no significant interaction between the effects of perceived importance of a task and interference/distraction on memory.
