​A statistical estimate of the standard deviation one would obtain from the distribution of an infinite number of estimates of the difference between the means of two groups is the ____.

Select one:

a.

standard error of the difference

b.

​estimated error

c.

​regression coefficient

d.

​correction factor

Standard deviation: An indicator of the variability of a set of scores in a sample around the mean of that sample.

Standard error: The spread of the averages around the average of averages in a sampling distribution.

Standard error of the difference: A statistical estimate of the standard deviation one would obtain from the distribution of an infinite number of estimates of the difference between the mean of two groups.

Regression coefficient: is a statistical measure of the average functional relationship between two or more variables. In that one variable is considered dependent and other one as independent.

Correction factor: A factor that is multiplied with the result of an equation to correct for a known amount of systematic error.

By looking at the above definition the correct answer will be standard error of the difference.
