In this exercise, you'll improve this study so that the hypothesis is specific and falsifiable.
Hypothesis:
Video labels influence observer ratings of social interactions.
Study Design:
Researchers watch 20 videos of rat pairs interacting. Each video is labeled either 'sibling pairs' or 'stranger pairs.' All videos actually show stranger pairs. Researchers rate each video from 1-7 for friendly behavior (huddling, grooming, following).
