Chapter 12: Problem 19

Create and conduct a survey in your class. Organize the results in a two-way table. Then create a two-way table that shows the joint and marginal frequencies.

Short Answer

Expert verified

The survey has been conducted and the data has been organized into a two-way table. A second table with the joint and marginal frequencies has been created as well. These tables provide a comprehensive view of the collected survey data.

Step by step solution

Plan and Conduct the Survey

Identify a topic of interest to survey. Design a survey that will provide data on two variables. These variables will constitute the rows and columns of the two-way table. Once the survey is ready, administer it to the class and collect the responses.

Organize Data into a Two-Way Table

Create a two-way table to display the collected data. The rows of the table should represent one of the variables and the columns should represent the other. Each cell in the table should represent the count of observations that fall into a specific combination of the row and column categories.

Calculate Joint Frequencies

Joint frequencies are simply the counts of observations falling into each specific combination of the row and column categories, which were recorded in Step 2. They show the frequency of each combination of the two variables.

Calculate Marginal Frequencies

Marginal frequencies are the totals for each row and each column. They can be calculated by summing up the joint frequencies across each row and each column respectively.

Create the Table with Joint and Marginal Frequencies

Create another two-way table similar to the one in Step 2. However, in this table, include an extra row and an extra column for the marginal frequencies. The cell corresponding to a row and column represents the joint frequency of that combination of variables, and the extra row and column display the marginal frequencies.
