How do you interpret the data in a two-way table?

Back

To interpret data in a two-way table, look at the counts in each cell to understand the relationship between the two variables, and calculate totals and percentages as needed.

What does it mean if a two-way table shows a higher frequency in one category?

Back

A higher frequency in one category suggests a stronger association or preference for that category among the surveyed group.

Front

How can you calculate probabilities from a two-way table?

Back

Probabilities can be calculated by dividing the frequency of a specific outcome by the total number of observations in the table.

Front

What is the marginal total in a two-way table?

Back

The marginal total is the sum of the frequencies for each row or column, representing the total count for that category.

Front

What is a conditional probability in the context of a two-way table?

Back

Conditional probability is the probability of an event occurring given that another event has already occurred, often calculated using the relevant row or column totals.

Front

How do you find the joint frequency in a two-way table?

Back

The joint frequency is found in the cells of the table, representing the count of occurrences for the combination of the two categorical variables.

Front

What is the purpose of using a two-way table in surveys?

Back

Two-way tables are used in surveys to summarize and analyze the relationship between two categorical variables, making it easier to identify patterns and trends.
