How do you calculate the percentage of a specific outcome in a two-way table?

Back

To calculate the percentage, divide the frequency of the specific outcome by the total frequency and multiply by 100.

Front

What is relative frequency?

Back

Relative frequency is the ratio of the frequency of a particular outcome to the total number of outcomes, often expressed as a decimal or percentage.

Front

How can you find the total number of respondents in a two-way table?

Back

Add the frequencies of all categories in the table to find the total number of respondents.

Front

What does it mean if a two-way table shows a high percentage of a certain outcome?

Back

A high percentage indicates that the outcome is common among the surveyed population, suggesting a strong relationship between the variables.

Front

What is the purpose of using two-way tables in statistics?

Back

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

Front

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

Back

To interpret data, look for patterns, compare frequencies, and calculate percentages or relative frequencies to understand relationships.

Front

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

Back

The total row and column provide the overall counts for each category, which are essential for calculating percentages and understanding the data distribution.

Front

How can you use a two-way table to answer application-based questions?

Back

By analyzing the frequencies and calculating percentages or relative frequencies, you can draw conclusions about the relationship between the variables.

What is the formula for calculating the percentage of a subgroup in a two-way table?

Back

Percentage = (Frequency of subgroup / Total frequency) x 100.
