Question

You recently completed an experiment concerning the effects of carbs on happiness. One group of 11 people are assigned a high carb diet, another group of 11 people are assigned a moderate-high carb diet, another group of 11 people are assigned a moderate-low carb diet, and a final group of 11 people are assigned a low carb diet. If I find that I fail to reject the null hypothesis, what might my next step be?

Group of answer choices

Change my analysis and alpha to make the finding significant and then run post-hoc tests.

1. Run multiple dependent measures t-tests to see if there are any significant differences between particular groups

2. Run multiple independent samples t-tests to see if there are any significant differences between particular groups

3. Change my hypothesis to see if I can find something significant with a different hypothesis for this study

4. Run home and binge-watch Bridgerton because there is nothing else that should be done statistically
