by judging the closeness of the data points to the line. |

Construct and interpret a two-way table summarizing data on two categorical variables collected from the same
subjects, using relative frequencies calculated for rows or columns to describe possible associations between the two
variables. |
Arkansas Academic Standards:
8.SP.A.4

- Understand that patterns of association can also be seen in bivariate categorical data by displaying frequencies and relative frequencies in a two-way table
- Construct and interpret a two-way table on two categorical variables collected from the same subjects
- Use relative frequencies calculated for rows or columns to describe possible association between the two variables
Example: Two-Way Frequency Table
Example: Two-Way Relative Frequency Table
For example: Students might be asked to interpret from the tables above, if they saw an SUV in the parking lot, would it be more likely to belong to a male or female?
Note: Suggested connections for instruction: Standard 8.NS.1. On the Two-Way Relative Frequency Table, it is not required to include the fractional representation for each value, this is simply provided as an example.

Find probabilities of compound events using organized lists, tables, tree diagrams, and simulation. Understand that, just as with simple events, the probability of a compound event is the fraction of outcomes in the sample space for which the compound event occurs. Represent sample spaces for compound events using methods such as organized lists, tables, and tree diagrams. For an event
described in everyday language (e.g., "rolling double sixes"), identify the outcomes in the sample space which compose the event. |
