Frequency Tables Objective: To construct frequency tables.

Frequency Tables At the end of this lesson you should be able to answer the following question. Can you determine mean, median, or mode from a frequency table?

Frequency Tables A frequency table is a graphical display showing how often a particular event occurred.

Frequency Tables A frequency table is a graphical display showing how often a particular event occurred. The intervals allow you to see the frequency distribution of the data or how many pieces of data are in each interval.
