![]() Final result: Standard error of meanĪs a result, the standard error of mean is 1.693, as calculated in cell E3. ![]() Select cell E3 and enter the formula for SEM :įigure 3.COUNT function returns the number of data points in a sampleīy using the above formula, we can calculate the standard error of mean through these steps:įigure 2.SQRT function returns the square root of a number.STDEV.S function returns the standard deviation of a sample.We can calculate the standard error of mean by using the functions STDEV.S, SQRT and COUNT. There is no built-in function that directly computes for the standard error of mean. Its formula is the quotient of standard deviation and the square root of sample size. SEM is not as popular as standard deviation, and it is sometimes just referred to as “standard error”. It is an estimate of the deviation of a sample mean from the population mean. The Standard Error of Mean, also known as SEM is another measure of variability of data. Calculate standard error of mean (SEM) in Excel
