How to Calculate the Standard Error of Mean (SEM)? Or, we can say, ↓ Standard Error = ↑ Sample Representative of Population If the standard error here is smaller, there is a good chance of the sample being more representative of the entire population. For instance, the standard error of the mean reflects the standard deviation of the distribution of sample means gathered from a sample. The term usually refers to the standard deviation of different sample statistics in research, such as the mean or median. The standard error can sound all Greek to most students, even researchers, but with the help of this guide, you will undoubtedly get the most out of it. It is used in various fields from mathematics to economics and statistics, but it is of utmost importance in econometrics, where it is utilized by researchers for hypothesis testing and performing regression analyses. In simpler words, it measures how accurately a sampling distribution depicts a population.

It is the approximate standard deviation of a statistical sample population for estimating the accuracy, efficiency, and consistency of a sample.

Standard error, abbreviated as SE, is a mathematical tool used to assess the variability in statistics.
