Solve problems involving linear law

Back

•Interpret r (the correlation coefficient) as data points are added, moved, or removed.

•Interpret the sum of the squared residuals while manually fitting a line.

•Interpret the sum of the squared residuals of a best-fit line as a data point is added, moved, or removed.

•Compare the sum of the squared residuals between a manually fitted line and the best-fit line.

•Determine if a linear fit is appropriate.
