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

How do you calculate relative frequency?

Back

Relative frequency is calculated by dividing the frequency of a specific outcome by the total number of observations.

Front

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

Back

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

Front

What does it mean if a percentage is calculated from a two-way frequency table?

Back

It indicates the proportion of a specific group within the total population represented in the table.

How can you find the percentage of students who eat breakfast between ages 10-13 from a two-way frequency table?

Back

Identify the frequency of students aged 10-13 who eat breakfast, divide it by the total number of students, and multiply by 100.

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 results of a two-way frequency table?

Back

Interpretation involves analyzing the frequencies and percentages to understand the relationship between the two variables.

Front

What is the formula for calculating the percentage of a subgroup in a two-way frequency table?

Back

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

Front

What does a high relative frequency indicate in a two-way frequency table?

Back

A high relative frequency indicates that a particular outcome is common within the context of the data being analyzed.

Front

How do you identify a conditional probability from a two-way frequency table?

Back

Conditional probability can be identified by focusing on the subset of data relevant to a specific condition and calculating the frequency of the desired outcome within that subset.
