It's a statistic measure calculated from the sampling distributions where the large size samples or proportions reduces the SE of a statistic proportionally and vice versa.

Setup the test of significance or hypothesis for large & small sample size (student's t & Z statistic) to measure the reliability of sample & population parameter and the estimation the confidence interval for population parameter are some of the major applications of standard error.

It is one of an important & most frequently used functions in statistics & probability. In other words, it's a numerical value that represents standard deviation of the sampling distribution of a statistic for sample mean x̄ or proportion p, difference between two sample means (x̄ 1 - x̄ 2) or proportions (p 1 - p 2) (using either standard deviation or p value) in statistical surveys & experiments. It shows how effective the selected sample size n is in the statistical experiments or the reliability of experiment results with respect to the sample size. We guarantee a connection within 30 seconds and a customized solution within 20 minutes.In probability & statistics, the standard deviation of sampling distribution of a statistic is called as Standard Error often abbreviated as SE. Standard Error is calculated using the formula given below Standard Error s / n Standard Error 2.44 / 10 Standard Error 0.77 Therefore, the standard error of the sample mean is 0.77.

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. Calculate the standard error of the mean for a sample size of 49. Example: Assume the population standard deviation is 36. The Standard Error of Mean, also known as SEM is another measure of variability of data. The Standard Error Calculator uses the following formula: SE x s / sqrt( n ) Where: SE x is the standard error of the mean, s is the standard deviation of the sample, sqrt is the square root, n is the sample size.
