Two Way Frequency Tables

Front

What is a two-way frequency table?

Back

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

Front

What does the term 'joint frequency' mean in a two-way frequency table?

Back

Joint frequency refers to the count of occurrences for a specific combination of categories from both variables in a two-way frequency table.

Front

How do you calculate the total frequency in a two-way frequency table?

Back

To calculate the total frequency, sum all the individual frequencies in the table.

Front

What is 'relative frequency' in the context of a two-way frequency table?

Back

Relative frequency is the ratio of the joint frequency of a specific category to the total frequency, often expressed as a percentage.

Front

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

Back

Marginal frequency is found by summing the frequencies across a row or down a column, representing the total for that category.

Front

What is the formula for calculating joint relative frequency?

Back

Joint relative frequency = (Joint frequency) / (Total frequency) * 100%.

Front

What information can be derived from a two-way frequency table?

Back

A two-way frequency table can provide insights into the relationship between two categorical variables, including joint frequencies, marginal frequencies, and relative frequencies.

Front

How can you determine the number of students who prefer a specific combination of options from a two-way frequency table?

Back

Look for the cell that corresponds to the intersection of the row and column representing the specific options.

Front

What is the significance of the grand total in a two-way frequency table?

Back

The grand total represents the overall count of all observations in the table, used for calculating relative frequencies.

Front

How do you interpret a relative frequency of 20% for a specific category?

Back

A relative frequency of 20% indicates that 20% of the total surveyed individuals fall into that specific category.
