  1. For basic statistics using CASIO fx-MS CASIO fx-Tl CASIO fx-W CASIO fx-100S When you are successfully in statistics mode, a symbol should appear at the top of your screen. sd MODE 2 For basic statistics using CASIO fx-570W When you are successfully in statistics mode, a symbol should appear at the top of your screen. 1 DRG 2nd F sd For basic statistics using SHARP Advanced D.H.L. calculator When you are successfully in statistics mode, a symbol should appear at the top of your screen. Stat MODE MODE 1 To use your calculator for calculating statistics, you must become familiar with the process of changing into and out of the required mode

  2. 1 DRG 2nd F SHIFT AC = MODE 2 SHIFT C DEL 2nd F SHIFT MODE = 1 BEFORE ENTERING ANY DATA It is important that you are not carrying any previously entered data into the next calculation, so make sure that your memory is cleared. THE FIRST OPERATION YOU DO WHENEVER YOU START TO PROCESS ANY DATA IS TO CLEAR ANY EXISTING DATA. THIS DOES NOT HAPPEN SIMPLY BY TURNING THE CALCULATOR OFF!!!

  3. RCL RCL C 3 SHIFT 1 = 3 RCL 0 To check the number of entries:

  4. Entering the data Data may be entered as individual scores, or in multiples of each score. To enter the data individually : M+ Enter the following data 250 300 225 210 275 202 290 320 208 225 210 250 275 225 210 When you have entered them all, check that the number of entries is correct ie

  5. And now the statistics and their respective symbols These symbols are different on the Sharp calculator To understand the meaning of these statistics, refer to other resources

  6. S-SUM SHIFT To calculate the variance, get the s.d. and then use: = 1 3 = SHIFT S-VAR 2 1 = SHIFT S-VAR 2 2 = SHIFT S-VAR 2 3 = To find them on your Casio fx-82MS calculator:

  7. C RCL To calculate the variance, get the s.d. and then use: = SHIFT SHIFT SHIFT 1 2 3 = = = To find them on the Casio fx-82TL and 570W calculators:

  8. To calculate the variance, get the s.d. and then use: = SHIFT SHIFT SHIFT 1 2 3 = = = = RCL 3 To find them on your Casio fx-82W calculator:

  9. 0 RCL To calculate the variance, get the s.d. and then use: = 4 6 5 RCL RCL RCL To find them on your Sharp DHL calculator:

  10. 3 RCL To calculate the variance, get the s.d. and then use: = 1 2 3 RCL RCL RCL To find them on your Casio fx-100S calculator:

  11. Using the data you have already entered, find the mean, standard deviations and variances for both population and sample All correct? Great work. If you have not the correct answers, then you will have to re-enter Your data – after CLEARING the previous entries. If you have a Casio fx-82MS, you can check your data entries and correct them.

  12. Try this example: 32.10, -45.00, 66.00, 2.53, -8.10, -51.25, 12.10, 18.00, 21.00, -31.00, 2.10 If you do not have these answers, first check how you entered the negative values. You must use the +/- or (-) key for negative values – NOT the operation “minus” key.

  13. Casio fx 82 MS, TL and W and 570W: Casio 100S M+ x-value SHIFT ’ f x-value × f M+ M+ 2 × 6 M+ 2 SHIFT ’ 6 Sharp D.H.L x-value 2nd F f M+ STO 2 2nd F 6 M+ STO To enter multiple or grouped data • Enter six 2’s on your calculator • What if you had to enter 20, 50, …? • Now try:

  14. Casio fx 82 MS, TL and W and 570W: Casio 100S x-value × f M+ M+ Sharp D.H.L x-value SHIFT ’ f x-value 2nd F f M+ STO PRACTISE
