The statistical display menu choices depend on the type of statistical calculations you intend to do. **Please Read the manual**. Note: When you finish entering data press AC key and renter the stat mode.

Scientific calculator

The most basic scientific calculator can do simple 1-variable statistics. Usually you put the calculator in**STATistics Mode, then CLEAR all statistics data that may already be stored.**

You enter a data value by typing in the number then pressing a key marked DATA. The calculator may display the number 1 for the 1st point. Then as you enter more values, the display shows number that increase by 1.

Once you finish entering data values, you may have to press AC button to exit the data entry phase.

Then you look for the second function (2nd 2ndF, or SHIFT) of some keys. The one marked with an x with a bar on top give the average, the one with marked n give the number of data entered. You may have other keys with the Greek Capital Letter SIGMA. They give various results such as sum of squares, etc.**Check your manual for more details.**

Newer calculators allow you to use the frequency if there are repeated values. I cannot say more because I do n ot have the make and model of the calculator.

Find the formula for the correlation coefficient and use the calculator to calculate it.

You can also use the calculator to do statistics. It has some keys to retrieve the statistical values calculated. You will find r among them.

Please do read your manual to learn how to do statistics.

Do not go buy another calculator because this one does 1-var, 2-var, as well as some regression models, and some distributions.

For 1-var and 2-var statistics read on.

TO COMPUTE STANDARD DEVIATION AND 2-VAR STATISTICS.

I assume you know the theory. I will show you the key strokes

For 1-Var statistics

Press [MODE][3:STAT] [1:1-VAR]. You are ready to enter values in the X column.

Enter a number and press [=]. Cursor jumps to second number to enter.

Keep entering numbers and pressing [=] till all numbers are in. Press the [=] key after the last one.

**Press
[AC] key to clear the screen.**

Press [SHIFT] [STAT] (above digit 1.) then [5:Var]. Screen displays the statistical variables 1:n ;2: x bar; 3: x sigma n; 4:x sigma n-1.

Press the number corresponding to the statistical value you want, ex 1:n . The variable appears on screen. Press [=] and it will be displayed.

To display another variable press [SHIFT][STAT][5:Var][ 1,2, 3, or 4] .

To access the sum of squares sigma x^2 and the sum of data sigma x press[SHIFT][STAT][4:SUM] then [1: for sigma x^2] or [2: for sigma x]. Press [SHIFT][STAT][6:MinMax] to access minX and maxX.

For 2-var statistics

To perform 2 variable statistics you press [MODE][3:STAT] and any of the other regression options (except 1:1-Var). A two column template opens where you enter the X and Y values. When finished entering data, press [SHIFT][STAT][5:Var]. to access the different statistics. As I assumed above, you should be able to recognize what each variable means.

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.

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.

Hello,

Not knowing what kind of probability calculations you want to perform, I can only show you how to access the distributions that this calculator has to offer.

After you enter your data and do the usual statistics, you press SHIFT STAT and select 7:Distr. You get acces to

1: P(

2:Q(

3:R( and

4: X to t, the variate.

See the exemples in the Appendix to the user's manual, in particular #059.

Hope it helps.

Me too I don't undertand how to use the statistical functions of this calculator. for example, if I want to calculate the standard deviation of a series data, I first begin by switching mode to "Stat", then I choose 2 for Quad. There's now the words "Stat 2" written at left on the screen, and "0" written at right. After, what do I have to do to calculate the standard diviation ?

And do I have to enter my data in the calculator befor to switch it to the Stat Mode ?

I'm totally confused...

If you can answer yourself or refer me to a website with full clear explanation, I would be very thankful to you.

PS. I'm not an anglophone, so be understanding...
