WASP (Write a Scientific Paper): Parametric vs. non-parametric tests.

Data may be normally distributed in which case standard and relatively familiar tests may be used for inferential testing. Or data may be non-normally distributed, such as ordinal data, in which case, non-parametric tests are usually advocated. This paper will review current thinking with regard to these tests, and the appropriateness of their application/s. [ABSTRACT FROM AUTHOR]
