Results will be given.
t is the value for your t-test
df is the degrees of freedom
˜1 is the mean from list 1
n1 is the number of values in list 1
˜2 is the mean from list 2
n2 is the number of values in list 2
Sx1 is the standard deviation for list 1 (square this number to get the variance)
Sx2 is the standard deviation for list 2

USING TI-84 (OR TI-83) CALCULATOR FOR STATISTICS
Calculating 2:
1. Press 2ND and x-1 . Select “EDIT”, then ENTER to display the MATRIX[A] screen.
2. Enter the number of rows, then move to the next number and enter the number of
columns.
(In this example, we would have 2 X 4).
3. Use  to move the cursor to the table and enter the observed frequencies into each cell.
(Press ENTER to advance to the next cell).
4. Press 2ND , MODE after entering all the cell values.
5. Press 2ND and x-1 . Select “EDIT”, then use  to move the cursor to [B]. ENTER
6. Follow steps 2 and 3 above, this time entering the values for the expected frequencies.
7. Press 2ND , MODE after entering all cell values.
8. Press STAT and select “TESTS”.
9. Select “C: 2-Test” and ENTER.
10. Verify that Observed is matrix A and Expected is matrix B.
