Definitions:

Z-statistic

The Z-statistic is a type of standard score that indicates how many standard deviations an element is from the mean, used in hypothesis testing for normal distributions.

Standard Error

A measure that describes the distribution of sample means around the population mean in a sampling distribution.

Standard Deviation

A measure of the amount of variation or dispersion of a set of values; indicates how much the values in a data set differ from the mean.

Variability

A measure of how much scores in a data set differ from each other and from the mean, indicating the spread or dispersion of the data points.
