Standard Error

A measure of the variability or dispersion of a sampling distribution.

Margin of Error

The largest anticipated discrepancy between the actual population parameter and its estimate derived from a sample.

Normal Distribution

A symmetric, bell-shaped distribution of data in which most of the observations cluster around the central peak and the probabilities for values further away from the mean taper off equally in both directions.
