A researcher wants to see if her class is significantly higher than the national average on IQ. She obtains the mean and SD of the national averages from the CDC website.

Choose 10 students who want to go to clown school. Before they begin clown school, measure their ability to balance a ruler on their noses in the morning and in the afternoon. Then test this ability, both in the morning and in the afternoon, when they complete clown school

If you were testing three different recipes for cheesecake on a group of taste testers, what test would you use to see if there are any differences in ratings given to the three recipes?

A researcher tests 21 participants with a 100 mg dose of a drug, 20 participants with a 200 mg dose of a drug, and 22 participants with a placebo to examine effects on anxiety among women. If there is a significant effect of drug, what test would you use to see which groups differ?

A researcher investigated whether one person’s mood influences another person’s mood. The researcher randomly divided the participants into two groups. Participants in the first group interacted with a happy person. Participants in the second group interacted with a sad person. After the interaction, the researcher measured how happy the participants were. What test would she perform to determine if there were any differences resulting from interacting with the happy vs. sad person?
