At the beginning of class, Rob and I switched. He monitored Chemistry and I taught Statistics how to create a stem plot or a box plot. We entered data (2,4,6,8,10,12) into L1 of Stats, graphed the stem plot, calculated one variable (1 Var) statistics and used the TRACE function on the stem plot or box plot to locate the quartiles and median. We repeated with new data (5,10,15, 20, 25, 30). The short-cut to set the Window or Range is Zoom 9 for STAT functions.
We reviewed definitions for mean, median, mode, quartile, a five point summary, box plot, examples. They drew a bar chart or histogram based on the data in the book.
