# Question

Let’s see how students and faculty compare on a basic statistical question. Zuckerman, Hodgins, Zuckerman, and Rosenthal (1993) surveyed 550 people and asked a number of questions on statistical issues. In one question a reviewer warned a researcher that she had a high probability of a Type I error because she had a small sample size. The researcher disagreed. Participants were asked, “Was the researcher correct?” The proportions of respondents, partitioned among students, assistant professors, associate professors, and full professors, who sided with the researcher and the total number of respondents in each category were as follows:

(a) Who do you think was correct?

(b) What do these data tell you about differences among groups of respondents? (Note: The researcher was correct. Our tests are specifically designed to hold the probability of a Type I error at a, regardless of the sample size.)

For the data in Exercise 20.5 we could say that 3 out of 10 residents used fewer hypotheses the second time and 7 used more. We could test this with x2. How would this differ from Friedman’s test applied to those data? Rerun the analysis in Exercise 20.7 using the normal approximation. In Exercise 20.7Post your question
