A chi-square test for independence is being used to evaluate the relationship between two variables. If the test has df = 2, what can you conclude about the two variables?
Added by Juan Manuel S.
Step 1
- The degrees of freedom for a chi-square test of independence is calculated as: \[ df = (r - 1) \times (c - 1) \] where \(r\) is the number of rows (categories) in one variable and \(c\) is the number of columns (categories) in the other variable. Show more…
