hi is there any guru programmer in c# that can help me with codes for calculating mean, median and mode of numbers.

What have you come up with? At least you should have done something so where are your codes that "aren't working"

@Fayimora is right, you should at least try something first and then guys here could help you finetune, and @omo_to_dun is also right, what you are trying to achieve is not exactly rocket science. But in case you really are pressed for time, or unable to fathom something on your own, a quick yahoo or google search can help you (sometime, it pays not to reinvent the wheels).

I find this link, that seems to do what you want.

and the post and code itself is as follows:

This is untested, but feel free to use as you see fit. For more extensive
statistical/math computations like Bessel functions, likelihood estimators,
and so forth, you might want to check out NMath. I've favored readability
over raw speed here, but this should be very fast.

///// Begin code.
using System;
using System.Collections;

public class MathAverages
{
// Computes the median x~ of a set of values X. O(1) implementation,
public static float Median(float[] values)
{
int size = values.Length - 1;
return ((values[size/2] == values[size/2 + 1]) / 2);
}

// Computes the mode set x{} of a set of values X. O(n) implementation.
public static float[] Mode(float[] values)
{
Hashtable h = new Hashtable();
int count = 0;
foreach (float value in values)
{
h[value]++;
if (h[value] > count)
count = h[value];
}

ArrayList modeValues = new ArrayList();
foreach (DictionaryEntry e in h)
{
if (e.Value >= count) modeValues.Add(e.Key);
}

return (float[])modeValues.ToArray(typeof(System.Single));
}

// Computes the arithmetic mean x-bar of a set of values X. O(n)
implementation.
public static float Mean(float[] values)
{
float sum = 0;
foreach (float value in values)
{
sum += value;
}
return sum/(values.Length);
}
}
///// End code.

tanks soo much fayimora, omo to dun u learn wen someone gives you a way all the same tanks for the reply.

omo_to_dun:

This is the problem that we have in Nigeria: instead of guiding the man on how to write the code, you handed it to him. How is he supposed to learn?

I got tired of trying to point this out, No one listens!
