That was a great lesson from Luke Wilcox! Here are my take-aways and teacher comments:

Last Night’s homework:

Example “Which AP Class has a higher GPA?”:

Questions 1-4 is SOCS or CUSS and BS (use Context at least one time during the process) when describing a distribution
Median and IQR go together with skewed distributions and Mean and SD go together with symmetrical distributions
Review the 1.5(IQR) rule for outliers, nice review
Notice that you also use SOCS for comparing a distribution, for this you can just state “center” (you do not have to pick a type of center)
#6 is a reference to a 2 Sample t-test from section 10-2.

Example of a two way table for “Course and College Plans”:

Segmented Bar Graphs should have a key
#4 highlights how each category should be compared to be “safe” for full credit
Notice the clever way the LW converts the SBG to a Mosaic Plot to show the difference in sample sizes for the two groups
#6 Chi Square Test (Chapter 11) is NOT on the 2020 AP Exam

Try the check your understanding homework that he gives at the end for Tuesday’s lesson if you can.

Please email me any time with any question, comments, thoughts.

Take care!!
