Answer #1

The chi square test of independence is a hypothesis test which is used to test the relationship between two nominal or categorical variables, This test involves in the usage of a contingency table, wherein Observed values are given and expected values are calculated as per the given contingency table.

Therefore Option a: A contingency table analysis.

___________________________________________

None of the other 3 tests the relationship between 2 nominal variables.

A goodness of fit test checks if a set of data comes from a population from which it is sampled.

ANOVA (Analysis of variance) compares the means of 3 or more quantitative variables

A regression analysis is used to check the strength of the relationship between a dependent variable and 2 or more independent variables.
