Represent data on a scatter plot, fit functions to the data, and assess fit

Represent data on two quantitative variables on a scatter plot, and describe how the variables are related. 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, quadratic, and exponential models. 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.


  • Create and read scatter plots

    In this lesson you will learn how to create and read scatter plots by plotting points and examining the form, direction and strength of any pattern.
