Question about Casio FX-9750GPlus Calculator

# 5 number summaries and casio 9750 plus

I just got this calculater for a statistics class. We are calculating sets of numbers to obtain 5 number summaries that show Q1, Q3 mode etc. My problem is that I was able to get my first set of numbers to calculate but after that I do everything the book says and get nothing. I tried erasing the memory thinking that might have something to do with this but that did not help. Any suggestions

SOURCE: Standard Deviations

This calc will do standard deviations. In the manual it is on page 2 and also on page 40.

SOURCE: Mean and standard deviation

Mode - 2 - STAT - 1(VAR) Then put your data: 25,34,13

Then press AC which is the clear button and then SHIFT - 1(STAT) - 5(VAR) 2 (X) =

Voila!

Alot of people have this doubt, so I might as well make it clear.

Press the 10^x button (while pressing SHIFT, of course; it's exactly above the LOG button) followed by the number whose antilog you desire.

Example :
Let's say we need antilog(-6.8),
1. Press SHIFT, followed by LOG (i.e 10^x); this'll display a 10 on the screen;
2. Type in -6.8;
3. Press "=";
4. This'll display 1.584893192x10^-7 as the solution, which is correct!
5. Bye, lol :P

### Hi,how can I calculate median using fx-570es plus?

The median is the number is the middle.

Using the calculator, you can follow the Statistical Calculations (Stat) on pages 22 and 23 of the attached manual. http://support.casio.com/pdf/004/fx-570_991ES_PLUS_E.pdf

However, it might be quicker to just put the numbers is order from lowest to highest and pick out the number in the middle.

For example, take the numbers 3, 5, 4, 7, 6, 4, 9.

Putting them in order, we get 3, 4, 4, 5, 6, 7, 9

There are 7 numbers so we want the 4th number (3 numbers to the right and 3 numbers to the left). In this case, the 4th number is 5 and that is our median, as half the numbers are lower than it and half the numbers are higher than it. It the number of numbers is even, you take the average of the two middle numbers.

Good luck,

Paul

### How can I reset my Casio FX-115 ES calculator to its default settings

There must be an error in what you report. You pressed MODE then 4: Base-N and now your calculator is in base-N calculation mode (the DEC, Hex, BIN, OCT) numeration keys are active.
To do statistics you must put the calculator in STATS mode.
Press MODE: You have 6 computational modes to choose from
1: COMP, the general computational mode
2:CMPLX, for calculation s with complex numbers,
3: STAT for statistics,
4: Base-N, binary, octal, decimal, and hexadecimal numeration
5: Equation, solving mode, etc..
For statistics, choose 3:STAT

### Can you please help me on how to calculate mean, median, mode, standard deviation calculation on casio fx-991ms scientific calculator

This will show you how to do statistics (calculate average, standard deviation, regressions etc.) as to the mode and median refer to the definitions.

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.

### Casio 9850

Definitely not by asking in a forum. You could get a walkthrough, but that's not solving the problem.
This one is down to reading the calculator manual and your textbook a bit, then satisfying yourself that your answer and the definitions for those types of average are in accord. Mode is clearly an oddball which would make more sense with more context, but for now just pick the most common number, which is a set: (7, 10, 11).
That sounded better than 'toss-up between 7, 10 and 11,' did it not?

### Statistics

Random number generators on computers are not really random. They need to be "seeded". If you seed the random number generator with the same seed each time you will generate the same list of numbers. A common technique in computer programming is to seed the random number generator with a value like the number of seconds that has occurred since midnight. This gives you the illusion of real random numbers.

Look up the word "Seed" in your calculator documentation and it will most likely tell you how this is accomplished on the TI calculators.
