Wed nes day

Tonight, explore some influential points...please complete "The Wandering Point" activity provided in class.

Remember, you should never have more than 5 points in your calculator. So to start you'll add the point (3, 4) and find the new correlation and slope. Then, plot this point on the small graph on the top right (it counts by 2's) to find the size of the residual (small, medium, large, or 0).

When you're done, delete the point (3,4) and replace it with (8,6), and so on....

Then, use the table to answer 3 and 4 at the bottom.

Tomorrow we'll use this to finish our discussion of influential points and outliers! Woo!
