Z-tests are closely related to t-tests, but t-tests are best performed when an experiment has a
small sample size. In addition, t-tests assume that the standard deviation is unknown, while ztests assume that it is known. If the standard deviation of the p
How would you explain the analysis of variance, assuming that your audience has not
had a statistics class before?
ANOVA tells you if a set of features reduces the amount of unexplained information more by
having the groupings than by leaving out all grou

What is an interaction? Describe an example and identify the variables within your
population (work, social, academic, etc.) for which you might expect interactions?

DQ 2 WK 3
Researchers routinely choose an alpha level of 0.05 for testing their hypotheses. What are
some experiments for which you might want a lower alpha level (e.g., 0.01)? What are some
situations in which you might accept a higher level (e.g., 0.1)?

How would you explain the analysis of variance, assuming that your audience has not had a
statistics class before?
So I must explain what the word ANOVA means, as I am a novice at statistics and analysis of variance too.
ANOVA is comparing three
