[S.ID.6] Interpreting Categorical and Quantitative Data #6

Objectives

Summarize, represent, and interpret data on two categorical and quantitative variables. [Linear focus; discuss general principle.]

• • S.ID.6 Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.

  • S.ID.6a Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear and exponential models.

    • S.ID.6b Informally assess the fit of a function by plotting and analyzing residuals.

    • S.ID.6c Fit a linear function for a scatter plot that suggests a linear association.
