One way of organizing data is by constructing a frequency distribution table. A tally mark is used to record how often a particular score or number occurs. The number of times a score or number appears is called the frequency.
To construct a frequency distribution table:
a. list the scores or numbers from highest to lowest (or lowest to highest),
b. use tally marks to record how often each score or number appears, and
c. count the marks and record it in the frequency column.
