s2 is the sample standard variance. Working... To calculate the standard error of any particular sampling distribution of sample means, enter the mean and standard deviation (sd) of the source population, along with the value ofn, and then Dividing the sample standard deviation by the square root of sample mean provides the standard error of the mean (SEM).

Solved Example The below solved example for to estimate the

For example, the median of data set 1,2,3,4,5 is the middle value 3, which separate the lower half 1,2 from the higher half 4,5. The reason N-2 is used rather than N-1 is that two parameters (the slope and the intercept) were estimated in order to estimate the sum of squares. The below step by step procedures help users to understand how to calculate standard error using above formulas.

Recall that the regression line is the line that minimizes the sum of squared deviations of prediction (also called the sum of squares error). The median of data set 1,2,3,4 is (2 + 3) / 2 = 2.5.
