Aidecal AD-82MS Statistics Calculation

  • Mean and standard deviation – single data

X x

The formula for the mean is x = —


The formulas for the sample standard deviation are




l( X1 x)                                             (population)

n = \

Your calculator will calculate the mean and standard deviation for you (the population standard deviation an or the sample standard deviation a 1 – in data calculations you will usually use the sample standard deviation.)

On the Casio fx-82MS, a and s are found in s-VAR. The positions of keys needed are shown on the diagram below.

To find the mean and standard deviation,


firstly you must access the statistics mode of the calculator by using the keys CD once followed by [   ] SD will appear in the centre of the screen.

Note that once you are in the statistics mode, the keys shown within the blue lines are active. There are 3 such keys on the Casio iX-82MS. Make sure you can locate them. Before starting any computations always clear the statistic’s memories using Scl. Press

Aidecal AD-82MS

I will use the data set A (-5, 2, 3, 4, 11) to demonstrate the use of the calculator. Note that I


have shown the use of the (       )   key where   necessary.

Step 1: Input the observations.


Use the            key to input data (no  need to   press       (  )).


v—————————– ‘ dtlclj ————————————————– ‘ dtlclj ———————————————– ‘dt lclj ————————————————– ‘dt lclj————————————————– ‘——————————– ‘DTlCLJ

The display should read n = 5. (This means 5 observations have been input).

Step 3: Display the mean and standard deviation.



the display shows three alternatives

x x0 x„ ,

0 n-1

1 2 CO


gives x = 3





gives x0n = 5.099019514





gives xan-1 = 5.700877126


Example of calculation in Aidecal AD-82MS

Use your calculator to find the mean, standard deviation and variance for data set B: -18, 1, 3, 9, 20.

(the variance is the square of the standard deviation)

After you are in the statistics mode and cleared the statistics memories, the keystrokes required are:

and the display will read 3



and the display will read 13.87443693


and the display will read 192.5 The mean is 3, the standard deviation is 13.87 and the variance is 192.5.

4, 5, 60, 7, 9 and you meant to input 6 instead of 60. Press the                     key until the  display

reads x3 = 60, then press                     . You now have the correct data.

In the example below, the progressive calculations are shown simply to give you some understanding of the underlying processes – you should do one or two examples in detail and then check them by calculator.


  • Mean and standard deviation of frequency distribution

Given below is the frequency table for the weights (kg) of a random sample of 30 first year university female students. Find the standard deviation, the variance and the mean.

Graduate’s weight (kg) Frequency Cumulative


60 2 2
61 14 16
62 8 24
63 1 25
64 5 30


The calculations needed to obtain the standard deviation without statistical keys for these data are:

Sx2 = 602 x 2 + 612 x 14 + 622 x 8 + 632 + 642 x 5 = 114 495 Sx = 60 x 2 + 61 x 14 + 62 x 8 + 63 + 64 x 5 = 1 853

Sx2 – (Sx//n

n – 1

114 495 -(1 853) 730 = <114               -^11^


Thus:    s    = 1.2 kg and s2 = 1.4 kg2

_ Sx 1853 R1 „,

x – n ‘ -sir –618 kg

Note: In calculations like the above you should carry as many decimals as possible until the final result. The number of decimals to be retained at the end depends on the accuracy of the data values – one rule of thumb is to have one more decimal than in the original data.

Notice how the frequencies were used in the above calculation. Aidecal AD-82MS

The calculator usage now has a small modification because we have been given the frequencies for the variable values. (There is no need to input each single observation.)

The keystrokes required are:


The display should read n = 30.

shift rS-wrc-i —————————————————————————————————

and the display should read 61.766667

SHIFT rS-VAR-1 ———————————————————————————————-

and the display should read 1.1943353 [   ] and the display should read 1.4264369

Thus, as expected

5 = 1.2 kg, s2 = 1.4 kg2 and x = 61.8 kg

Exercise 6

Find the mean, standard deviation and variance of (a) The annual rainfall data for the years 1971 – 1990
