Based on the information provided, identify the appropriate statistical analysis for each situation. When appropriate, identify the effect size you should calculate and any post hoc tests you might conduct.
1. We ask students how many Facebook friends they have, and we want to compare our results to the average reported by past research.
2. We want to test if students who interact with their professors via Facebook have more Facebook friends than those who do not interact with their professors via Facebook.
3. We want to test if men are more likely than women to have ever "friended" a professor on Facebook.
4. We have participants read three different scenarios, each describing a professor with varying policies about interacting with students on Facebook. The participants rate each of the professors on their credibility (7-point scale).
5. We want to test if participants own experience with professors on Facebook (defined as ever or never "friending" a professor) moderates the impact of the three different scenarios (described in question 4). |
