# Introduction to Two Way Tables

Two way tables are an important part of mathematical analysis, and are used to illustrate the relationship between two sets of variables. In a two way table, the rows represent one set of variables and the columns represent another set. By looking at the intersection of the two sets, you can determine how the two variables are related. In lesson 3 skills practice, we are going to look at two way tables and how they can be used to analyze data.

## Creating a Two Way Table

The first step in creating a two way table is to identify the two sets of variables that you are going to be looking at. Once these variables have been identified, you can create the two way table. The rows of the table should correspond to the first variable, and the columns should correspond to the second variable. When creating the table, it is important to make sure that all of the necessary information is included in the table, as this will help you when you are analyzing the data.

## Analyzing a Two Way Table

Once the two way table has been created, it is time to analyze the data. This can be done by looking at the numbers that are in the cells. For example, if the first variable is age and the second variable is gender, then you can look at the numbers in the table to see how many people of each age and gender are represented in the data. By looking at the numbers in the table, you can determine relationships between the two sets of variables.

## Interpreting a Two Way Table

Once the data has been analyzed, it is time to interpret the results. This can be done by looking at the relationships that have been identified. For example, if the first variable is age and the second variable is gender, then you may be able to identify that people of a certain age are more likely to identify as a certain gender. By interpreting the data, you can get a better understanding of the relationship between the two variables.

## 

Two way tables are a useful tool for analyzing data and identifying relationships between two sets of variables. In lesson 3 skills practice, we looked at how to create and analyze two way tables. We also looked at how to interpret the results of the analysis. By understanding how to use two way tables, you can gain a better understanding of how two sets of variables are related.
