Stephanie Schmid – North

Teacher leads students through a series of questions related to linear regression and interpretation of linear models.


Iowa Core Standards:


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.


Interpret the slope (rate of change) and the intercept (constant term) of a linear model in the context of the data.


Compute (using technology) and interpret the correlation coefficient of a linear fit.
