well standard deviation is the term used in descriptive statistics.where as standard error is used in inferrential statistics.

Descriptive statistics are one we will do a population study.Inferrentisl statistics are one in which we will take a small section of population and infer these results to the general population.

SE = S/square root N N is the sampe of the population we take in the study.

right.
SE is also part of the formula for finding the CI. (confidence interval).

CI = Mean +/- Z (SD/square root of N)
