Two-Way Frequency Tables

Front

What is a two-way frequency table?

Back

A two-way frequency table is a statistical tool that displays the frequency of different outcomes in two categorical variables, allowing for the analysis of the relationship between them.

Front

What does relative frequency represent?

Back

Relative frequency represents the ratio of the frequency of a specific outcome to the total number of observations, often expressed as a percentage.

Front

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific category by the total number of observations and multiplying by 100.

Front

What is the purpose of a two-way frequency table?

Back

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

Front

What information can you derive from a two-way frequency table?

Back

You can derive counts, relative frequencies, and insights about the relationship between the two variables, such as trends and patterns.

Front

How can you identify the most preferred category in a two-way frequency table?

Back

You can identify the most preferred category by comparing the frequencies or relative frequencies of each category.

Front

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

Back

The total row and column provide the overall counts for each category, which are essential for calculating relative frequencies.

Front

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

Back

Interpreting data involves analyzing the frequencies and relative frequencies to understand the relationship between the two variables.

Front

What is an example of a categorical variable?

Back

An example of a categorical variable is 'age group' (e.g., 18-25, 25-49, 50+).

Front

What does it mean if a certain age group has a higher relative frequency for a specific preference?

Back

It means that a larger proportion of that age group prefers that specific option compared to others.
