#### 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 summarizing data 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.

Learning Targets and Learning Criteria

Students are successful when they can…

• construct a scatter plot by plotting ordered pairs on a coordinate grid representing the relationship between two data sets.
• describe patterns in the plotted points such as clustering, outliers, positive or negative association, and linear or non-linear association and describe the pattern in the context of the measurement data.
• explain the patterns of association of scatter plots of bivariate data in the context of the data sample.
• compare two data sets of variability by comparing graphs and explain the significance of any visual overlap.
• explain why it makes sense that the greater the variability, the more visible the overlap on graphs presenting two numerical data sets.
• model and compare two real-world data sets by measuring the difference between centers and expressing it as a multiple of a measure of variability.
• compare and contrast two populations by using the means and/or medians of data collected from random samples using appropriate vocabulary.
• compare and contrast two populations by using the mean absolute deviations and/or interquartile ranges of data from random samples.
• read and interpret data from statistical representations (box-and-whisker plot, line/dot plot).
• understand the use of a two-way table to display bivariate categorical data.
• create a two-way table to record the frequencies of bivariate categorical values.
• determine the relative frequencies for rows and/or columns of a two-way table.
• use the relative frequencies and context of the problem to describe possible associations between the two sets of data.
