To do list for Tuesday: 1. Read pp. 43, 44; 2. Decide on the number of classes (bins) you think are appropriate for the data set. 3. Create a frequency table for the data, a relative freq. table for the data, and a histogram for the data. 4. Now using your phone, research the “2^k” rule for classes. 5. Repeat #2 and #3 using this “2^k” rule! 6.Use page 45 in your book to help you learn how to get a histogram on your calculator. 7. Take notes on the first part of chapter 3…pp. 43-48

Watched this video (HERE); Hmwk: finish reading the chapter and taking notes
Fri 9/7 Notes check ; book cover check; worksheet…front side with home-runs….make a dot plot, use 2^k rule to create a freq. table and histogram, and make a stem and leaf plot….THEN on the back side…make a back-to-back stem plot for per 2 and 6 snake eyes data; compare M/M/M/R and if you had to guess…which class has a high stdev? (StDev measures the spread of data)
Mon 9/10 Turned in hmwk; video on box plots (HERE)…much more with box plots tomorrow. time to work on Ch 3 #5-13
Tue 9/11 Dr. Hartman talked and went over a bunch of things…discussed details of Ch 2 categorical methods to describe data (main point: only stats we see is based on the whole 100%…can’t find mean or median)…discussed details of Ch 3 quantitative methods including the importance of the histogram (to help with shape center and spread) and the basics again of Mean/STDEV vs Median/IQR…talked about how the indiv values of data show up for stem plots and dot plots…but not for histograms/box plots. We then spent the rest of our time with the details of box plots, finding outliers, and using our calculator; finish up #5-13
Wed 9/12 Dr. Hartman was gone for district pep rallies; work on problems in this order: #15, 16, 17, 19, 20, then 40  (but make a box plot for part a and then do b, c, d), then 23, 25, 26, 27, 41 and then #21
