Answer:
Standard error
Step-by-step explanation:
The standard deviation of the distribution of sample means is called the standard error of the means.
It is denoted by: [tex]\sigma_{\bar X}[/tex]
The standard error is calculated using the formula: [tex]\sigma_{\bar X}=\frac{\sigma}{\sqrt{n} }[/tex]
where n is the sample size and [tex]\sigma[/tex] is the population standard deviation.
