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.

How do you calculate the total number of surveyed individuals from a two-way frequency table?

Back

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

Front

What does the term 'relative frequency' mean?

Back

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

Front

How do you find the percentage of a subgroup in a two-way frequency table?

Back

To find the percentage of a subgroup, divide the frequency of that subgroup by the total frequency and multiply by 100.

Front

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

Back

The purpose of a two-way frequency table is to organize data to show the relationship between two categorical variables and to facilitate comparison.

Front

What is the formula for calculating the percentage of individuals who meet a specific criterion in a two-way frequency table?

Back

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

Front

How can you determine the number of individuals who do not belong to a specific category using a two-way frequency table?

Back

Subtract the frequency of the specific category from the total frequency to find the number of individuals not in that category.

Front

What is an example of a categorical variable?

Back

An example of a categorical variable is 'favorite ice cream flavor,' which can take on values like chocolate, vanilla, or strawberry.

Front

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

Back

To interpret the data, analyze the frequencies to identify trends, relationships, and patterns between the two categorical variables.

Front

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

Back

The total row and total column provide the overall frequencies for each category, helping to summarize the data and calculate percentages.
