What is a crosstab?
A cross tab, also known as a crosstabulation or contingency table, is a statistical tool that is often used in the analysis of survey or poll data. It is a table that displays the relationship between two or more variables by showing the frequency or percentage of respondents who fall into different categories for each variable.
For example, if a poll is conducted to determine the political preferences of different age groups, a cross tab could be used to show the percentage of respondents in each age group who support a particular political party. The rows of the table would represent the different age groups, and the columns would represent the different political parties. The cells of the table would show the percentage or frequency of respondents in each age group who support each party.
Cross tabs can be useful in a variety of contexts, including identifying trends and patterns in survey data, comparing the responses of different subgroups within a population (such as different age groups or geographic regions), and testing hypotheses about the relationship between different variables.
In summary, a cross tab is a statistical tool that is used to analyze survey or poll data by displaying the relationship between two or more variables through the frequency or percentage of respondents who fall into different categories for each variable. It is often used to identify trends and patterns in survey data, compare the responses of different subgroups, and test hypotheses about the relationship between variables.
