Student Statement
I am able to create a linear regression equation given a table of values. I can use the correlation coefficient to describe the overall fit of the data and can use the equation to predict values.
Common Core Standards
S-ID.B.6: 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 function for a scatter plot that suggest a linear association.
S-ID.C.8: Compute (using technology) and interpret the correlation coefficient of a linear fit.
The following are examples of mistakes that should give you an idea what types of mistakes I am looking for at each level. There are a variety of possible errors while solving problems like this, so this is not an exhaustive list.
