One item on a questionnaire asks students how many times in a typical week they eat at a fast-food restaurant.  The responses for a sample of n = 10 students are summarized in the frequency distribution. What is the best measure of central tendency for these data?X                             f5 or more          24                             33                             22                             11                             10                             1

What is the critical value for a repeated measures ANOVA with N=25, 4 levels for factor A, dfWG = 52, and an alpha level of 0.05?

With alpha = .05, what is the critical t value for a one-tailed, one sample t-test test with n = 15?

Which of the following is expected if the null hypothesis is true for an analysis of variance?

What value is estimated with a confidence interval using the repeated-measures t statistic?

Which of the following has the greatest correlation?

If other factors are held constant, what is the effect of increasing the sample variance?

Which of the following is expected if the null hypothesis is true for an analysis of variance?

An ANOVA test rejects the null hypothesis, proving that the results are significant. It is determined that eta squared=.35. Interpret this value.
