How do you write a c program to calculate mean variance and standard deviation?

Answer 1

Program in CHere is a program in C to calculate mean variance and standard deviation:

#include

#include

void main()

{

float a[50],sum=0,vsum=0,mean,variance,sd;

int n,i;

printf("Enter the no of valus");

scanf("%d",&n);

printf("Enter the no of valus");

for(i=0;i

{

scanf("%f",&a[i]);

}

for(i=0;i

{

sum=sum+a[i];

mean=sum/n;

}

for(i=0;i

{vsum=vsum+((a[i]-mean)*(a[i]-mean));

variance=vsum/(n-1);

sd=sqrt(variance);

}

printf("Arithmeti mean=%f",mean);

printf("Variance=%f",variance);

printf("Standard=%f",sd);

getch();

}
