Definitions:

Normal Distribution

A bell-shaped frequency distribution curve where most of the occurrences take place around the central peak and the probabilities of extreme occurrences taper off equally on both sides.

Continuity Correction

An adjustment made to a discrete distribution when it is approximated by a continuous distribution, often used in binomial distribution approximations.

Standardized Value

A score that has been transformed to have a mean of zero and a standard deviation of one, also known as a z-score, enabling comparison across different scales or distributions.

Wilcoxon Rank Sum Test

A non-parametric statistical test used to compare two independent samples to assess if their population mean ranks differ.
