My girlfriend is a dietitian, she is taking another supplementary course or something. I don't know what the course is, I'm guessing. She is in another city and almost done with the course and only has to submit her papers for approval.

• Mode, Median, Mean, Standard Deviation, Variance Calculator in C. Ask Question Asked 8 years, 10 months ago. C program through mysql pull.
• Mean and Standard Deviation for the Binomial Distribution. The binomial probability is a discrete probability distribution, with appears frequently in applications, that can take integer values on a range of (0, n ), for a sample size of (n ). The population mean is computed as: mu = n cdot p Also, the population variance is computed as.

Yesterday she sent me some data she had collected. Her professor had asked her to:

I have given the simple C program for calculating sample and population standard deviation for a set of numbers. The other related linkes are, Calculate Mean Calculate Median Calculate Mode Calculate Range Calculate Variance Calculate Standard Deviation. $ cc standard-deviation.c -lm $./a.out Enter number of elements: 5 Input 5 values 32 35 31 33 34 Mean is 33.000000 Standard Deviation is 1.414214 « Previous Next » C Program Examples.

1. Find The Mean & Standard Deviation of some of the data she had collected.
2. Type them out in 2 decimal places. (She sent me this '3.2821 .45588 how can I write these in 2 decimal places?')
3. Put the Plus-Minus sign before them.
She wanted to know how to do those.

Number 3 is easy enough, the Plus-Minus sign can be found in the character map on any Windows system (Start>All Programs>Accessories>System Tools>Character Map on Windows 7), also, the character code for that character is 241.
So if she was typing in the character in MS Word, she would have to hold down the Alt key, type in 241 on the Num-Pad (doesn't have to be Num-Pad for Laptops), and let go of the Alt key and find ± (Incidentally, you can use that to type in any of the ASCII characters).
I was a bit confused on #1. I didn't know what Mean & Standard Deviation meant. She led me to a page:
http://www.mathsisfun.com/data/standard-deviation-formulas.html
She also told me she had a lot of data to find the Mean and SD for. So I wrote a little program that will solve it for her if she inputs the numbers.
As usual, just copy paste into Code::Blocks and press F9 to run the program.
Sample:
Code:
#include <stdio.h>
#include <stdlib.h>
#include <strings.h>
#include <math.h>

int get_key(void);

system('mode 158,77');

printf('Enter your values (upto 50). Press Enter after each. Press F1 to calculate. Esc to exitn');

for(loop=0;loop<50;loop++)
{
x=0;
