APPENDIX 1: OBTAINING THE MEAN AND VARIANCE
ON THE TI-30Xa AND CASIO fx-300SA CALCULATORS

We consider the data for the children in group 1 (example in Section 1.2), which is as follows:

10, 13, 7, 12, 13, 11, 8, 14, 9, 12

TI-30Xa
STEP DISPLAY
1. Enter 10 and press ∑+ n=1 (indicates 1 data point has been entered)
2. Enter 13 and press ∑+ n=2 (indicates 2 data points entered)
3. Enter 7 and press ∑+ n=3
4. Enter the remaining 7 data points, and at that point the display will show
n=10, indicating that 10 data points have been entered.
5. Press 2ND and then X2 10.9 (this is the mean)
6. Press 2ND and then 2.33095 (standard deviation)
7. Press X2 5.4333 (variance)
CASIO fx - 300SA
1. Press SHIFT and AC 0 (clears all statistical registers)
2. Press MODE and 2 0 and DEG AND SD underneath
3. Press 10 and M+ 10 and DATA in the upper left corner
4. Press 13 and M+ 13 and DATA in the upper left corner
5. Press 7 and M+ 7 and DATA in the upper left corner
6. Enter the remaining data points; after the last data point has been entered
there will be a 12 in the display.
7. Press shift and 1 10.9 (mean)
8. Press shift and 3 2.33095 (standard deviation)
9. Press X2 5.4333 (variance)
