Front

What is a positive correlation?

Back

A positive correlation means that as one variable increases, the other variable also increases.

How can you determine the number of individuals in a specific category using a two-way table?

Back

You can find the total count in the intersection of the relevant row and column in the two-way table.

Front

What is the purpose of a two-way table?

Back

The purpose of a two-way table is to summarize data and show the relationship between two categorical variables.

What does the term 'marginal frequency' refer to in a two-way table?

Back

Marginal frequency refers to the totals found in the margins (the last row and column) of a two-way table.

Front

What is a conditional frequency in a two-way table?

Back

Conditional frequency is the frequency of a specific category given a condition, often found by dividing the frequency of the intersection by the total of the row or column.

Front

How do you calculate the total number of observations in a two-way table?

Back

You can calculate the total number of observations by summing all the frequencies in the table.

Front

What is the significance of the intersection of a row and column in a two-way table?

Back

The intersection of a row and column shows the count of individuals that fall into both categories represented by that row and column.

How can you use a two-way table to find probabilities?

Back

You can find probabilities by dividing the frequency of a specific cell by the total number of observations.
