1. Researchers compared the effectiveness of a mood induction technique (exposure to depressing film footage) across 3 different groups of 11 participants each: 1) 0 minutes exposure (Control Group), 2) 10 minutes exposure, & 3) 20 minutes exposure.The response variable is the score on the Beck Depression Inventory (higher score = more depressed mood).

• Is the results warrant additional analysis (post hoc analyses)? Please help me explain why or why not,andexplain why such analyses would be needed.
