Definitions:

Population

The entire pool from which a statistical sample is drawn and to which the results of analysis will be generalized.

Finite Population Correction Factor

The term \( \frac{(N - n)}{(N - 1)} \) that is used in the formulas for s_x and s_p whenever a finite population, rather than an infinite population, is being sampled. The generally accepted rule of thumb is to ignore the finite population correction factor whenever n/N ≤ .05.

Standard Error

The standard deviation of the sampling distribution of a statistic, most commonly of the mean.

Computing

Computing refers to the process of utilizing computer technology to complete a task or solve problems.
