Two Way Tables

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.

The purpose of a two-way table is to summarize data and show the relationship between two variables, making it easier to analyze and interpret the data.

To calculate the percentage of a category, divide the frequency of that category by the total frequency and multiply by 100.

A sample is a subset of a population used to represent the entire group in statistical analysis.

A population is the entire group of individuals or items that is the subject of a statistical study.

A high correlation indicates that as one variable changes, the other variable tends to change in a predictable way.

Conditional probability is the probability of an event occurring given that another event has already occurred.

To find the probability of an event, divide the number of favorable outcomes by the total number of outcomes represented in the table.

Marginal frequencies are the totals for each category, while joint frequencies are the counts for specific combinations of categories.

The probability of two independent events occurring together is the product of their individual probabilities.
