Answer:
Test program is written below.
Explanation:
import java.util.Scanner;
public class MeanAndMedian {
public static double mean(double[] x) {
double avg = 0;
for (int i = 0; i < x.length; ++i) {
avg += x[i];
}
return avg / x.length;
}
public static double deviation(double[] x) {
double m = mean(x);
double total = 0;
for (int i = 0; i < x.length; ++i) {
total += (x[i] - m) * (x[i] - m);
}
return Math.sqrt(total / (x.length - 1));
}
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
System.out.print("Enter 10 numbers: ");
double x[] = new double[10];
for (int i = 0; i < x.length; ++i) {
x[i] = in.nextDouble();
}
System.out.printf("The mean is %.2f\n", mean(x));
System.out.printf("The standard standardDeviation is %.5f\n", deviation(x));
}
}
