In this lesson,Â the studentÂ will learn how to set up a two-way frequency table from two categorical variables and use the two-way frequency table to calculate frequency counts and relative frequency. The vocabularyÂ terms learned in this lesson are *tw**o-way frequency table, relative frequency, joint frequency, marginal frequency,* and *conditional frequency. *This lesson covers only a portion of the standard. The teacher should complete the standard with a follow-up lesson in which students will make data tables and then use the data to explore probability.
