Students take a more sophisticated look at using a linear function to model the relationship between two numerical variables. In addition to how well the model fits by analyzing residuals. S.ID.6b should be focused on linear models, but may be used to preview

quadratic functions in Unit 5 of this

course.

Summarize categorical data for two categories in two-way frequency tables. Interpret relative frequencies in the context of the data (including joint, marginal, and conditional relative frequencies). Recognize possible associations and trends in the data.

Fit a function to the data; use functions fitted to data to solve problems in the context of the data.

Informally assess the fit of a function by plotting and analyzing residuals.

Fit a linear function for a scatter plot that suggests a linear association.
