(Note that we’ve skipped “Class 12” in our numbering–I postponed it until later in the semester.)

Please complete before the next class.

Make sure that you’ve completed all previous HW first.


Four Scatterplots


FPP

Read chs. 7 and 8 of FPP and do the assigned review exercises here.

Make sure that if I give you several sets of paired observations, such as X = [1, 2, 3, 4, 5] and Y = [1, 3, 2, 4, 6], you can calculate and interpret the correlation coefficient. You can test yourself by logging in to your Google account and then copying this Google Sheet. Also, make sure you can roughly link a particular scatterplots with it’s correlation coefficient (see Exercise 9.1 in the notes below).

Notes

Read chs. 7, 8, and 9 from my notes. There’s substantial overlap with chs. 7 and 8 from FPP, so you may be able to skim some of the content. Make sure that you can draw a scatterplot in R (see Exercise 8.1), compute a correlation coefficient in R (see Exercises 9.4 and 9.5)
