Make up a set of data for a 2 3 2 design that has no main effects but does have an interaction.
Answer to relevant QuestionsDescribe a reasonable experiment in which the primary interest would be in the interaction effect. By comparing the formulae for η2 and ω2, tell when these two different statistics would be in close agreement and when they would disagree noticeably. The results in Exercises 17.1 through 17.4 are certainly extreme, and the statistics look unusual. What might trouble you about these data? Write a short paragraph describing the results of the analysis of the data in Exercise 18.1. Use the data in Exercise 19.8 to demonstrate how chi-square varies as a function of sample size. (a) Double each cell entry and recompute chi-square. (b) What does this have to say about the role of the sample size in ...
