C# Program to Find the Standard Deviation

CSharp 14 Views 1 Min Read

In statistics, the standard deviation is a measure of the amount of variation or dispersion of a set of values. In this task, we will write a C# program to find the standard deviation of a set of numbers.

Problem Statement

Write a C# program to find the standard deviation of a set of numbers. The program should take input from the user in the form of a set of numbers. The program should display the standard deviation of the numbers as output.

C# Program to Find the Standard Deviation

using System;
using System.Collections.Generic;
using System.Linq;

class Program
{
    static void Main(string[] args)
    {
        Console.WriteLine("Enter the numbers separated by spaces: ");
        string input = Console.ReadLine();
        string[] numbers = input.Split(' ');

        List<double> values = new List<double>();
        foreach (string number in numbers)
        {
            values.Add(double.Parse(number));
        }

        double mean = values.Average();
        double sumOfSquares = 0;
        foreach (double value in values)
        {
            sumOfSquares += Math.Pow(value - mean, 2);
        }

        double standardDeviation = Math.Sqrt(sumOfSquares / values.Count);
        Console.WriteLine("Standard Deviation: {0}", standardDeviation);
    }
}
