Definitions:

Significance Level

The threshold below which the p-value must fall for the null hypothesis to be rejected in statistical testing.

Sample Standard Deviation

A statistic that measures the dispersion or variability of a sample dataset around its mean.

Sample Mean

The average value of a sample set from a population, often used as an estimate of the population mean.

Standard Deviation

A quantification of the level of diversity or variability in a collection of values, demonstrating how much the values differ from their average.
