Definition Of Standard Error Of Estimate
a normally distributed sampling distribution whose overall mean is equal to zero and whose standard deviation ("standard

error") is equal to square.root[(sd2/na) + (sd2/nb)] where sd2 = the variance of the source population (i.e., the square of the standard deviation); na = the size of sample A; and nb = definition margin of error the size of sample B. To calculate the standard error of any particular sampling distribution of sample-mean differences, enter the mean and standard deviation (sd) of the source population, along with the values of na andnb, and then click the "Calculate" button. -1sd mean +1sd <== sourcepopulation <== samplingdistribution standard error of sample-mean differences = ± sd of source population sd = ± size of sample A = size of sample B = Home Click this link only if you did not arrive here via the VassarStats main page. ©Richard Lowry 2001- All rights reserved.

the mean estimates the variability between samples whereas the definition sampling error standard deviation measures the variability within a single sample. For example, you have definition of standard deviation a mean delivery time of 3.80 days with a standard deviation of 1.43 days based on a random sample of 312 delivery http://vassarstats.net/dist2.html times. These numbers yield a standard error of the mean of 0.08 days (1.43 divided by the square root of 312). Had you taken multiple random samples of the same size and from the same population the standard deviation of those different sample means would http://support.minitab.com/en-us/minitab/17/topic-library/basic-statistics-and-graphs/hypothesis-tests/tests-of-means/what-is-the-standard-error-of-the-mean/ be around 0.08 days. Use the standard error of the mean to determine how precisely the mean of the sample estimates the population mean. Lower values of the standard error of the mean indicate more precise estimates of the population mean. Usually, a larger standard deviation will result in a larger standard error of the mean and a less precise estimate. A larger sample size will result in a smaller standard error of the mean and a more precise estimate. Minitab uses the standard error of the mean to calculate the confidence interval, which is a range of values likely to include the population mean.Minitab.comLicense PortalStoreBlogContact UsCopyright © 2016 Minitab Inc.

The standard error of the difference (SE) is given by: √(σ21/Σx1 + σ22/Σx2), where σ1 and σ2 are the two standard deviations, and Σx1 and Σx2 are the sums of the two samples.
