This means it measures the extent to which estimated test or examination scores are spread around a true score.ДЄ more formal way to look at it is through the 1985 lens of Aera, APA, and NCME. The standard error of measurement accounts for the consistency of scores within individual subjects in a test or examination. Using this formula, we can deduce the standard error of the mean as follows: Suppose that the standard deviation of observation is 15 with a sample size of 100. In other words, it quantifies how much variation is expected to be present in the sample mean that would be computed from every possible sample, of a given size, taken from the population. The standard error of the mean accounts for the difference between the sample mean and the population mean. There are five types of standard error which are: Using standard error, a researcher can estimate the efficiency and consistency of a sample to know precisely how a sampling distribution represents a population. In addition, standard error serves as a measure of accuracy. In other words, it shows the extent to which a statistical measure varies from sample to population. Researchers depend on this statistical measure to know how much sampling fluctuation exists in their sample data.

For example, the standard error of the mean measures how far the sample mean (average) of the data is likely to be from the true population mean-the same applies to other types of standard errors.

The standard error allows you to compare two similar measures in your sample data and population. You can also think of it as the standard deviation of your sample in relation to your target population. The standard error is a statistical measure that accounts for the extent to which a sample distribution represents the population of interest using standard deviation.
