Question

Which of the following is NOT true for conducting a hypothesis test for independence between the row variable and column variable in a contingency table?

Question content area bottom

Part 1

Choose the correct answer below.

The number of degrees of freedom is

(r−1)(c−1),

where r is the number of rows and c is the number of columns.

The null hypothesis is that the row and column variables are independent of each other.

Tests of independence with a contingency table are always right-tailed.

Small values of the

χ2

test statistic reflect significant differences between observed and expected frequencies.

Definition Definition Visual representation of the relationship between two or more categorical variables. A contingency table is a categorical version of the scatterplot, which is used to visualize the linear relationship between two variables.
