Definitions:

Statistical Significance

Rejection of the null hypothesis when an outcome has a low probability of occurrence (usually .05 or less) if, in fact, the null hypothesis is correct.

Probability Level

The threshold of significance, usually denoted as alpha (α), indicating the likelihood of observing the data if the null hypothesis is true.

Systematic Variance

The part of variance in a set of data that is attributable to identified sources or factors, as opposed to random or error variance.

Error Variance
