Frequency table
Any table that displays the frequencies of values of one or more variables in a data set.
For a whole-number variable in a data set, a table showing each value of the variable and its corresponding frequency.
For a measurement variable in a data set, a table showing a set of class intervals for the variable and the corresponding frequency for each interval.
For a category variable in a data set, a table showing each category of the variable and its corresponding frequency.
A frequency table will often have an extra column that shows the percentages that fall in each value, class interval or category. See: one-way table, two-way table
