What is the standard deviation of a sampling distribution called?

Standard error.

Step-by-step explanation:

If the population is normally distributed , then the standard deviation of a sampling distribution of the sample mean " alt="\overline{x}" />" /> is known as standard error which depends on population standard deviation and the sample size (n).

It measure the variability in the sample statistics that happens by chance.

Thus, the standard deviation of a sampling distribution is called the standard error.

example 2 – simplify: step 1: completely factor both the numerators and denominators of all fractions. step 2: change the division sign to a multiplication sign and flip (or reciprocate) the fraction after the division sign; essential you need to multiply by the reciprocal. step 3 : cancel or reduce the fractions.
