Chapter 10: Statistics & Regression Calculations
• 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.
Note: • Either list input or parameter input may be used for tests other
than 01 χ
2
test, 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 χ
2
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 χ
2
test 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 χ
2
test.
The result is entered in mat
B.
χ
2
: χ-squared statistic for the
test
p: p value for the test
df: degrees of freedom
