Question

what is a two - way table used for?
a. finding the median of a data set
b. calculating the average of a data set
c. displaying data in a structured format to show interactions between two variables
d. summarizing a single variable

Explanation:

A two - way table, also known as a contingency table, is used to display the frequency distribution of two categorical variables. It helps in analyzing the relationship or interaction between the two variables. For example, if we have variables like "Gender" (Male/Female) and "Favorite Color" (Red/Blue/Green), a two - way table can show how many males prefer each color and how many females prefer each color. This structured display allows for easy comparison and identification of patterns or associations between the two variables. Options a (finding the median) and b (calculating the average) are related to measures of central tendency for numerical data and not relevant to two - way tables. Option d (summarizing a single variable) is incorrect as two - way tables deal with two variables.

Answer:

C. Displaying data in a structured format to show interactions between two variables
