What is a two-way table?

Back

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

What is the purpose of a marginal relative frequency?

Back

Marginal relative frequency shows the proportion of a single category in relation to the total number of observations, helping to understand the overall distribution.

Front

How do you calculate conditional relative frequency?

Back

Conditional relative frequency is calculated by dividing the frequency of a specific category by the total frequency of the condition being considered.

Front

What is joint relative frequency?

Back

Joint relative frequency is the proportion of observations that fall into a specific category for both variables, calculated by dividing the frequency of the joint occurrence by the total number of observations.

How do you find the total number of surveyed individuals in a two-way table?

Back

To find the total number of surveyed individuals, sum all the frequencies in the table.

Front

What does a frequency in a two-way table represent?

Back

A frequency in a two-way table represents the count of occurrences for a specific combination of the two categorical variables.

Front

What is the formula for calculating marginal relative frequency?

Back

Marginal relative frequency = (Total for a category) / (Grand total of all categories).

How can you identify the number of females surveyed from a two-way table?

Back

Look for the total frequency in the row or column designated for females.

Front

What does a conditional relative frequency of 52% indicate?

Back

It indicates that 52% of the individuals who prefer basketball are females.

Front

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

Back

The grand total represents the total number of observations and is used as a denominator for calculating relative frequencies.
