Variance for accumulator. Validate that the following code, which adds the

Art [367]

Using the knowledge of computational language in JAVA it is possible to write a code that Validate that the following code, which adds the methods var() and stddev() to Accumulator, computes both the mean and variance of the numbers presented as arguments to addDataValue()

<h3>Writting the code:</h3>

import java.util.*;

public class Accumulator {

private static double m;

private static double v;

private static double st;

private static double s[]=new double[5];

private static int N;

private static int count =0;

public static void main(String[] args) {

// TODO Auto-generated method stub

Random r = new Random();

System.out.println("hello world");

for(int i=0;i<5;i++) {

double randomvalue = r.nextDouble();

addDataValue(randomvalue);

}

for(int i=0;i<s.length;i++) {

System.out.println("dataValue:"+s[i]);

}

mean();

System.out.println("mean:"+m);

var();

System.out.println("variance:"+v);

stddev();

System.out.println("standard deviation:"+st);

}

public static void addDataValue(double value) { // addes data values to array

s[count]=value;

count++;

}

public static double mean() { // returns mean

double sum=0.0;

for(int i=0;i<s.length;i++) {

sum+=s[i];

}

m = sum/s.length;

return m;

}

public static double var() { //returns variance

double mm = mean();

double t = 0;

for(int i=0;i<s.length;i++) {

t+= (s[i]-mm)*(s[i]-mm);

}

v= t/(s.length-1);

return v;

}

public static double stddev() { // returnsn the stardard deviation

st= Math.sqrt(var());

return st;

}
