 Description  
 Frequency Table:  A table for organizing a set of data that shows the number of times each item or number appears.
Example frequency table:

Assume that mathematics grades in a 13-student class are as fallows: A, B, B, B, D, A, A, C, C, C, D, D, B. The frequency table to summarize the distribution of grades is
 Grades  Frequency
 A  3
 B  4
 C 3
D 3


Above, for example, the row B-4 represents the information that 4 of the students have B in mathematics.

And that is all there is to creating a frequency table. Often, though, a frequency table is used simply as a stepping stone for creating other representations (line plots, stem-and-leaf plots, and histograms) of the same type of data.
