Answer 7

Friedman

Question 8

In a two variable statistical test; when the independent AND dependent variable are BOTH nominal or ordinal this is a ____ ____ test

Answer 8

chi square

Question 9

In a two variable statistical test; when the independent variable is nominal or ordinal and the dependent is continuous then it is a _____ or ____ test; it tests the null hypothesis that there is no difference between the groups versus that the groups differ or that at least one of the groups differ (only in an ANOVA with 2 or more levels)

Answer 9

Answer 12

correlation

regression

Question 13

The ____ ____ test is a continuation of the Wilcoxon Rank Sum test, at 2 groups it is much like the t-test and ANOVA, however it can handle MORE than two groups

With ______ test, the subjects give more than one value; for example, each individual receives BOTH injections and compares the 2

Answer 17

McNemar

Question 18
