Document Summary

Anova -> the more nhst tests (multiple t tests), the more likely we are to conclude that there is an effect when there isn"t one. Instruction pressure condition doesn"t see lots of benefit. > 50% articles reported simple main effects analysis but no significant interaction: 3 situations where errors occur, comparing es in experimental group/condition and control group/condition. ***you know main effects per level exist if the slope is different from m = 0, so in the bottom two there is only a main effect for level 2, while top two have two main effects. ***you know there is an interaction when two lines are significantly different from each other slope-wise, so all four images have interactions. Distinction between two alphas: experiment-wise error rate, type i error rate anywhere in analysis of experiment, recall each test a = . 05, 1 in 20 chance of rejecting null when it is true in the long run.
