How to select appropriate statistical test?

Abstract

Selection of appropriate statistical test is very important for
analysis of research data. Use of wrong or inappropriate
statistical test is a common phenomenon observed in
articles published in biomedical journals.[1-4] Wrong
statistical tests can be seen in many conditions like use of
paired test for unpaired data or use of parametric statistical
tests for the data which does not follow the normal
distribution or incompatibility of statistical tests with the
type of data, etc.[5] Because of the availability of different
types of statistical software, performing the statistical tests
become easy, but selection of appropriate statistical test
is still a problem.
