1. What does it mean ?

Measure the approximate standard deviation of statistical sample population

2. What does it tell?

It indicates how accurate the mean of any sample likely to be compared with population mean.

3. It's characteristic

The more data included in calculation of mean, SE tend to be smaller

4. Interpretation

Smaller SE exhibits higher representation of the sample to the population.

5. The Equation







6. Term

Standard error estimates the likely accuracy of a number based on the sample size

Standard error of the mean, or SEM, indicates the size of the likely discrepancy compared to that of the larger population
