The following terms are used by electrical engineers in statistical signal processing studies instead of typical statistician's terms.

Statistics Electrical engineering
Null hypothesis Noise only hypothesis
Alternative hypothesis Signal + noise hypothesis
Critical region Signal present decision region
Type I error False alarm (FA) (noted as )
Type II error Miss [1]

In other engineering fields, particularly mechanical engineering, uncertainty analysis examines systematic and random components of variations in measurements associated with physical experiments.
