A researcher would like to conduct a 4-week study using ANOVA for the results, the study is to see the effect of starting an antidepressant medication, starting a placebo, and starting a routine daily exercise program over a 4-week period to see if symptoms of depression decreased in the groups.
The research question(s)
The antidepressant medication is more effective in significantly reducing depression over a placebo, and a routine daily exercise.
3. Your predicted results
4. The results if a type I error occurred
We wrongly concluded that antidepressant medication is effective in reducing depression over a placebo, and a routine daily exercise when in fact truly there is no effect.
5. The results if a type II error occured
We wrongly concluded that antidepressant medication is not effective in reducing depression over a placebo, and a routine daily exercise when in fact truly there is a real effect.
