Faith community nurses need a basic understanding of common statistical tests and their interpretation to aid in the appraisal of research for evidence-based practice. The purpose of this article is to review statistical concepts, define common statistical tests, and interpret the results of statistical tests. Common statistical tests that measure differences in groups are independent samples t-test, paired sample t-tests, and analysis of variance. Common statistical tests that measure relationships are Pearson product moment correlation and chi-square.
