MODEL NO: SHARP EL-531VH or EL-531RH (ADVANCED D.A.L) STEP ONE: Select the statistics mode. Select MODE, this is done by pressing 2ndF followed by the DRG button and then select option 1 which is STATX. The modes are generally written on the top of the calculator. Make sure STAT x is on the screen. STEP TWO: Input the Data The simplest case is one variable. To input 3, 5, 4, 7, 1 you must do the following: 3[M+] 5[M+] 4[M+] 7[M+] 1[M+] Each time you enter a unit of data the calculator shows the count of the data entered so far. So if youve done the above, your calculator should show 5 or n=5. STEP THREE: Statistical Calculations x is the sample mean: [RCL] [4] xn the population standard deviation: [RCL] [6] xn1 the sample standard deviation: [RCL] [5] x2 the sum of squares of the sample data: [RCL] [+/-] x the sum of the sample data: [RCL] [.] n the number of items in the sample: [RCL] [0] STEP FOUR: Clearing the Data In order to start calculations on a new dataset the current memory must be cleared by selecting CA. This is done by pressing SHIFT and then DEL. STEP FIVE: Getting out of STAT Mode This is done by selecting 2ndF, MODE and then option 0 on the calculator which is NORMAL. Try the following: Try to get the mean and standard deviation of 37.75, 38, 37, 38.5, and 37.5. You should get a mean of 37.75 and a standard deviation of 0.5.

MODEL NO: CASIO fx-83 WA STEP ONE: Select the statistics mode. This is done by pressing the MODE button and selecting SD which is option 2 on this calculator. STEP TWO: Input the Data The simplest case is one variable. To input 3, 5, 4, 7, 1 you must do the following: 3[M+] 5[M+] 4[M+] 7[M+] 1[M+] STEP THREE: Statistical Calculations x is the sample mean: [SHIFT] [1] [=] xn the population standard deviation: [SHIFT] [2] [=] xn1 the sample standard deviation: [SHIFT] [3] [=] x2 the sum of squares of the sample data: [ALPHA] [(-)] [=] x the sum of the sample data: [ALPHA] [ ,,,] [=] n the number of items in the sample: [ALPHA] [hyp] STEP FOUR: Clearing the Data In order to start calculations on a new dataset the current memory must be cleared. This is done by pressing ALPHA, then MCL and nally =. STEP FIVE: Getting out of STAT Mode This is done by selecting MODE and then COMP which is option 1. Try the following: Try to get the mean and standard deviation of 37.75, 38, 37, 38.5, and 37.5. You should get a mean of 37.75 and a standard deviation of 0.5.

MODEL NO: CASIO fx-83 ES STEP ONE: Select the statistics mode. This is done by pressing the MODE button, then selecting STAT which is option 2 on this calculator and then 1-VAR which is option 1 on this calculator. STEP TWO: Input the Data The simplest case is one variable. To input 3, 5, 4, 7, 1 you must do the following: 3[=] 5[=] 4[=] 7[=] 1[=] STEP THREE: Statistical Calculations x is the sample mean: [AC] [SHIFT] [1] [5] [2] [=] xn the population standard deviation: [AC] [SHIFT] [1] [5] [3] [=] xn1 the sample standard deviation: [AC] [SHIFT] [1] [5] [4] [=] x2 the sum of squares of the sample data: [AC] [SHIFT] [1] [4] [1] [=] x the sum of the sample data:[AC] [SHIFT] [1] [4] [2] [=] n the number of items in the sample: [AC] [SHIFT] [1] [5] [1] [=] STEP FOUR: Clearing the Data In order to start calculations on a new dataset the current memory must be cleared.
