Statisticians' and engineers' cross-reference of statistical terms

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

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