I like them a bunch. Specific points worth liking:
-Illustrations of scatter plots for significant and non-significant relationships.
|Data does not support the old wive's tale that everyone goes a little crazy during full moons.|
-Explains the Third Variable problem.
|Simple, pretty illustration of the perennial correlation example of ice cream sales (X):death by drowning (Y) relationship, and the third variable, hot weather (Z) that drives the relationship.|
|Video games (X) influence aggression (Y) via the moderator of personality (Z)|
|In order to test the video game hypothesis without using diary/retrospective data collection, the video describes how one might design a research study to test this hypothesis.|
