- Teach the difference between frequency and relative frequency and how to make conversions between the two.

- Introduce how to organize categorical data in either a frequency table or contingency table.

- Show how to interpret both marginal and conditional distribution from a contingency table.

This packet defines what frequency distributions are, including frequencies and relative frequencies. It also introduces a contingency table, which is like a frequency distribution, except for 2 or more variables. There are videos on how to construct these, and examples at the end for you to create your own tables.
