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);
}
}Input / Output
