Students distinguish between categorical data and numerical data.
Students summarize data on two categorical variables collected from a sample using a two-way frequency table.
1. A survey asked the question “How tall are you to the nearest inch?” A second question on this survey asked, “What sports do you play?” Indicate what type of data, numerical or categorical, would be collected from the first question? What type of data would be collected from the second question?
Another random sample of 100 surveys was selected. Jill had a copy of the frequency table that summarized these 100 surveys. Unfortunately, she spilled part of her lunch on the copy. The following summaries were still readable:
2. Help Jill recreate the table by determining the frequencies for cells (c), (e), (j), and (q).3. Of the cells (c), (e), (j), and (q), which cells represent joint frequencies?
4. Of the cells (c), (e), (j), and (q), which cells represent marginal frequencies?
