A researcher randomly assigns 33 subjects to one of three groups.

• Group 1 receives technical dietary information interactively from an on-line website.
• Group 2 receives the same information from a nurse practitioner, while
• Group 3 receives the information from a video tape made by the same nurse practitioner.

The researcher looked at three different ratings of the presentation; difficulty, usefulness, and importance to determine if there is a difference in the modes of presentation.

Review the three Non-parametric test videos in the Calculations section of the Statistics Visual Learner media piece.

A researcher is examining preferences among four new flavors of ice cream. A sample of n = 80 people is obtained. Each person tastes all four flavors and then picks a favorite. The distribution of preferences is as follows. Do these data indicate any significance preferences among the four flavors Test at the .05 level of significance?

Is it true that parametric tests are generally more powerful than nonparametric tests If so, give two reasons why you might choose to use a nonparametric test instead of a parametric test.

PSY 520 Week 6 Discussion 2

Explain how the ANOVA technique avoids the problem of the inflated probability of making Type I error that would arise using the alternative method of comparing groups two at a time using the t-test for independent groups.
