Here is a link to virtual tiles, if you want them at home:

Residuals! 3/4

Tonight you will be reading about “residuals.”  This is an easy piece of data to compute, which mathematicians use to determine how precise a line of best fit matches a scatter plot.

Please complete problems 1 – 8 tonight for homework.
