What Is N In Printf?

Is standard deviation over N or N 1?

In statistics, Bessel’s correction is the use of n − 1 instead of n in the formula for the sample variance and sample standard deviation, where n is the number of observations in a sample.

It also partially corrects the bias in the estimation of the population standard deviation..

What is printf () in C?

“printf” is the name of one of the main C output functions, and stands for “print formatted”. printf format strings are complementary to scanf format strings, which provide formatted input (parsing). … Many languages other than C copy the printf format string syntax closely or exactly in their own I/O functions.

How do you print N?
