Comparing Two Categorical Variables

Question 6 • TN-Mathematical Reasoning for Decision Making (Supplement)

Which statements about segmented and side-by-side bar graphs are true? Choose two correct answers.Segmented and side-by-side bar graphs summarize the data distribution for a single categorical variable.Segmented and side-by-side bar graphs summarize the data distribution for two or more categorical variables.Segmented and side-by-side bar graphs can summarize conditional relative frequencies.Segmented and side-by-side bar graphs summarize the data distribution for associated categorical variables only.Segmented and side-by-side bar graphs never show an association between categorical variables.

Answer
A
Segmented and side-by-side bar graphs summarize the data distribution for a single categorical variable.
B
Segmented and side-by-side bar graphs summarize the data distribution for two or more categorical variables.
C
Segmented and side-by-side bar graphs can summarize conditional relative frequencies.
D
Segmented and side-by-side bar graphs summarize the data distribution for associated categorical variables only.
E
Segmented and side-by-side bar graphs never show an association between categorical variables.

Explanation

Segmented and side-by-side bar graphs compare categories across two or more categorical variables, so they can show how the variables’ distributions relate. They can also display conditional relative frequencies, such as the proportion in each category within a group. They are not limited to associated variables, and they can show whether an association appears.
