You've obtained a chi square of 34.56, and it's significant. You want to test how strong the relationship between these two variables is. You have a sample size of 75. You have a table with 2 rows and 4 columns. What's your Cramer's V?
Homework Answers
Formula for Cramer's V:
Here,
= 34.56
N = 75
Min(r - 1, c - 1) = Min(2 - 1, 4 - 1) = 1
Hence,
V = 0.6788

Fill in the blank You've conducted a two-way chi-square analysis that was statistically significant and resulted in a Cramer's Phi of .33, a medium overall effect size. Now you'd like to examine "where the action is," that is, which particular cells in the design deviate significantly from independence. To do so, the statistic you will calculate for each cell is called ____ , and is denoted by "R".
