1.8 2 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

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

Back

To calculate the total frequency, sum all the frequencies in the table, including both row and column totals.

Front

What is relative frequency?

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 specific category in a two-way frequency table?

Back

To find the percentage, divide the frequency of the specific category by the total frequency and multiply by 100.

Front

What does it mean if two variables are independent in a two-way frequency table?

Back

If two variables are independent, the occurrence of one variable does not affect the occurrence of the other variable.

Front

How can you determine the marginal frequency from a two-way frequency table?

Back

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

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 analyze the relationship between two categorical variables.

Front

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

Back

To interpret the data, look for patterns, relationships, and comparisons between the two categorical variables based on their frequencies.

Front

What is the formula for calculating relative frequency?

Back

Relative Frequency = (Frequency of the category) / (Total frequency) x 100.

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 counts for each category, helping to understand the distribution of data.
