11/10: Today we learned how to find the Median-Median line using the regression in our graphing calculators and also by hand
11/11: Continue working on finding the Median-Median line using only a scientific calculatorand fitting the best model for a given set of data using the regression capabilities in the graphing calculator. HW: Math II book - p 250: 3-6, 13; p253: 10, 13-14; p281: 1-7 and p282: 1-3, 5-7.
12/1: Collect your river data tonight so your are ready to share with the class tomorrow. You should actually have 7 lists of data but only put 6 in your calculator: L1 - Simple Random Sample; L2 - Vertical Stratified Sample; L3 - Horizontal Stratified Sample; L4 - Simple Random Sample (with irrigation); L5 - Vertical Statified Sample (with irrigation); L6 - Horizontal Stratified Sample (with irrigation) TI-Nspire USERS: to get to the random integer feature on your calculator - just type RANDINT(1,10,1) This will generate 1 random integer between 1 and 10.
12/2: Attached are the sheets filled out today with everyone's data. Download your class data and create box& whiskers plots and histograms for each of the two sampling methods assigned during class. Download 2nd Period River Data Download 3rd Period River Data Download 6th Period River Data
