Definitions:

Standard Error

Standard error measures the accuracy with which a sample distribution represents a population, using the standard deviation of the sample means.

Infinite Population

A theoretical concept where the population size is considered to be limitless for the purposes of statistical analysis.

Standard Deviation

A statistical measurement that quantifies the amount of variation or dispersion of a set of values.

Atomic Orbitals

Mathematical functions that describe the wave-like behavior of an electron in an atom, these orbitals determine the distribution of electrons around an atom’s nucleus.
