There are many different options for graphing data, which can be overwhelming even for experienced mathematcians. This time, the focus is on histograms and Venn diagrams that highlight the frequency of a range of data and overlap of data. Individuals learn to represent data in a frequency table and then create a picture of the data using a histogram. They then recognize overlap in categorical data and emphasize that intersection with a Venn diagram.
