In this Java program, you’ll learn how to Calculate Standard Deviation using the Java programming language.
How to Calculate Standard Deviation using JAVA?
Example 1:
RUN CODE SNIPPETpublic class Main
{
public static void main(String[] args)
{
double[] numArray = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };
double SD = calculateSD(numArray);
System.out.format("Standard Deviation = %.6f", SD);
}
public static double calculateSD(double numArray[])
{
double sum = 0.0, standardDeviation = 0.0;
int length = numArray.length;
for(double num : numArray)
{
sum += num;
}
double mean = sum/length;
for(double num: numArray)
{
standardDeviation += Math.pow(num - mean, 2);
}
return Math.sqrt(standardDeviation/length);
}
}OUTPUT
Standard Deviation = 2.872281
