Frequency Table

A frequency table is a type of table that is used to present values and their frequencies for a particular data set. It lists the possible values or outcomes of the category, and then it lists how many times each value or outcome is observed. As an example, the results of asking a group of ten people about their favorite animals can be presented in a frequency table.
Preference Frequency
Cats
Dogs
Quokkas
Turtles

Frequency tables can be used to describe frequency distributions. To help people understand the data in a frequency table, its data can be represented visually, among other methods, by using a bar graph for categorical data or a histogram in case of numerical data.
