The Story So Far

#include<stdio.h> #include<conio.h> #include<math.h> #define N 10 void main( ) { int i; float x, y, sx=0, sy=0, sxx=0, syy=0, sxy=0, a, b, c, r; for(i=0; i { printf("Enter values for x & y"); scanf("%f %f", &x, &y); sx = sx + x; sy = sy + y; sxx = sxx + x * x; syy = syy + y * y; sxy = sxy + x * y; } a = sxy-sx*sy/N; b = sqrt(sxx-sx*sx/N); c = sqrt(syy-sy*sy/N); r = a / (b*c); printf("Coefficient of correlation is %f\n", r); }
