Frequency Distributions
A frequency distribution is a table that pairs each item in a set of data with its frequency of occurrence (how often it appears).
Example:
Suppose you want to create a frequency distribution for the following data set: A, D, F, B, A, F, A, D, B, F, F, A, A, E, A, D, C, B, C, A, E, F.
Line the letters up on the left. Tally each occurrence and count the tallies in the right hand column.

C |
