Question

Write a program that will calculate and print the sum, mean, variance, and standard deviation
of 7 numbers. The numbers must be input as data. This input data must also be printed by the
program. If your seven numbers input have been named A, B, C, D, E, F, G, then the variance
may be computed as:
variance = [(A-mean)2
+ (B-mean)2
+ ... + (G-mean)2
]/6
and the standard deviation is the square root of the variance. (Hint: If you can't figure out
how to get the square root in C++ leave it out at

Answer 1

Hi,
I don't see what's your issue here, beside the fact that in the variance you should divide by 7, not 6.
