Chapter 10: Statistics & Regression Calculations Note: • 16 InputList and 17 InputStats specify the above input methods. 16 InputList: Sets the input mode to the statistic data list method 17 InputStats: Sets the input mode to the value input mode For example, press S E 1 6 E to set to the list input mode. 5. Press @ h to execute the hypothesis test. • Either list input or parameter input may be used for tests other than 01 χ2test, 05 TtestLinreg, 10 Ztest1prop, 11Ztest2prop, 14 Zint1prop and 15 Zint2prop. • To clear the contents entered in Freq, move the cursor to the list name then press D E. 01 χ2 test Uses the sample data from a two-dimensional table represented by a matrix. Example If mat A = 3 2 5 4 6 1 3 8 2 3 5 1 execute the χ2test and store the obtaining results in mat B. 1. Press S E 0 1. 2. Enter mat A as the Observed Matrix, and mat B as the Expected Matrix. Press @ m A 1 E @ m A 2. 3. Press @ h to execute the χ2 test. The result is entered in mat B. χ2: χ-squared statistic for the test p: p value for the test df: degrees of freedom 166
