How to do sigma notation?


The calculator cannot add the terms of a sequence. You need a graphing calculator that has that feature, or a calculator with a CAS (Computer Algebra System).

Hod do you put this calculator into statistical mode?


The 30XA doesn't have a statistical mode; all of the statistical functions are available at all times.

2nd [CSR] clears the statistical registers, Sigma+ adds a data point, Sigma- deletes a data point, 2nd [x-bar] gives the mean, 2nd [sigma-x-n] and 2nd [sigma-x-n-minus-one] give the population and sample standard deviation.

For full details, refer to the statistics section in the manual. If you don't have a manual, you can download a guidebook from

Hello. I just wanted to ask you how do I calculate the variance and standard deviation in my cfx9850GB plus. I had a quick look at the manual but I couldnt find the info. thankz .


This shows you how to enter your data and calculate some statistical values. Keep in mind that the variance is the square of the standard deviation.


In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the statistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.
Example: Enter the following values in List 1
1st line enter 90 [EXE]
2nd line 85 [EXE]
3 79 [EXE]
4 75 [EXE]
5 70 [EXE]
6 68 [EXE]
7 56 [EXE]

When finished you press [F2:Calc], then [F1:1Var] and the statistical results appear on screen.

Title of screen : 1-Variable
x bar =74.7142857
Capital Sigma x= 523
Capita Sigma X squared = 39851
x lower case sigma n = 10.5249945
x lower case sigma n-1= 11.3682934
n = 7
Scroll down with Down arrow to access other data
minX =56
Q1=68
Med =75
Q3=85
Xbar -x lower case sigma n =64.1892911
x bar x lower case sigma n = 85.2392802
maxX=90
Mod=90

All you have to do now, is to look at the theory you learned and interpret what these values mean.

How do I use the standard deviation function?


  1. Calculator must be in SD mode (standard deviation mode) :Press [MODE] [.]
  2. However, if [FIX] or [SCI] appears on display you must press [MODE][9] first.
  3. Data input always starts with [SHIFT][SAC], to clear the registers of old data.
  4. Type a number and press the [DATA] key, it is the [M+] key at the bottom right of keypad.
After you finish entering the data

Press [SHIFT] [9] (sigma n-1) to get sample standard deviation
Press [SHIFT][8] (sigma n] for the population standard deviation
Press [SHIFT] [7] (xbar) for the mean
Press [SHIFT] [6] (n) for the number of data entries
Press [SHIFT] [5] (capital sigma x) for the sum of values
Press [SHIFT] [4] (capital sigma x to y) for the sum of squares of the values

For additional information you might consider taking a look at the calculator manual.

Mean (x-bar), variance (s^2) and standard deviation (s)


Enter 1 then press the (SIGMA)+ button (SIGMA) looks like a sideways capital M ....its a Greek letter.

Then enter 2 and press the (SIGMA)+ button
Then enter the next value and press the (SIGMA)+ button

After you press the (SIGMA)+ button the calculator displays the number of numbers you have entered

Once all numbers of your sample have been entered press 2nd and the button corresponding to x-bar

sample st. dev is the (sigma)n-1 button (need to use 2nd button)
variance is (std. dev.)^2

population st. dev is the (sigma)n-1 button (need to use 2nd button)
variance is (std. dev.)^2
