How do I do this on the calculator?

Hello,

You must first enter the data you are doing statistics on.

After you finish entering the data, do as the figure below describes.

Hope it helps.

Hi,

a 6ya expert can help you resolve that issue over the phone in a minute or two.

best thing about this new service is that you are never placed on hold and get to talk to real repairmen in the US.

the service is completely free and covers almost anything you can think of (from cars to computers, handyman, and even drones).

click here to download the app (for users in the US for now) and get all the help you need.

goodluck!

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).

The syntax is

Sigma ( function (n),index n, starting value of index n, ending value of index n, increment of n).

If you omit the increment of the index the calculator will assume it is equal to 1

There isn't one. Press the "STAT VAR" button to bring up the statistics menu. "Sx" and "Sy" will give you the sample standard deviations, while "sigma x" and "sigma y" will give you the population standard deviations.

When I say "sigma" I mean the lower case Greek letter sigma, which looks like a lower-case "o" with a tail pointing to the right.

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.

Capital Sigma x= 523

Capita Sigma X squared = 39851

x lower case sigma n-1= 11.3682934

n = 7

Press 2nd [CSR] (shift-7) to clear the statistical registers. Use the Sigma+ key (just above STO) to enter data points. Use 2nd [Sigma-] to remove erroneous data points. Use 2nd [sigma x n] (shift-divide) to compute the population standard deviation, or 2nd [sigma x n-1] (just to the left of the previous key) to compute the sample standard deviation.

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

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.

Hello,

I am aware that the solution provided below is valid for the CFX/FX-9850G/GB/ but I will supply it. I remain convinced it will help you for your calculator.

In the main menu select [STAT] icon to enter Stat mode and display the statistical data lists. Use the satistical data lists to input data and perform statistical calculations. Use the arrows to move the highlighting around the lists.

Exemple: 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]
