It links nominal, ordinal, and interval/ratio outcomes to commonly used tests such as Fisher’s exact test, McNemar’s test, Mann-Whitney, Wilcoxon signed ranks, Kruskal-Wallis, Friedman’s test, Spearman’s rho, Pearson’s r, and corresponding ANOVA and repeated-measures ANOVA options. It also notes nonparametric alternatives for markedly nonnormal distributions or small samples, supporting evidence-based nursing practice.","Quick Guide to Bivariate Statistical Tests  \n\n| Level of measurement\u003Cbr>of dependent variable | Group Comparisons:\u003Cbr>Number of groups (the independent variable) |  |  |  | Correlational\u003Cbr>analyses\u003Cbr>(To examine\u003Cbr>relationship\u003Cbr>strength) |\n| --- | --- | --- | --- | --- | --- |\n|  | 2 Groups |  | 3+ Groups |  |  |\n|  | Independent\u003Cbr>Groups Tests | Dependent Groups Tests | Independent\u003Cbr>Groups Tests | Dependent Groups Tests |  |\n| Nominal (Categorical) | \u003Cbr>\u003Cbr>p. 401\u003Cbr>(or Fisher’s\u003Cbr>exact test)\u003Cbr>p. 402 | McNemar”s\u003Cbr>test\u003Cbr>p. 402 | \u003Cbr>p. 401 | Cochran’s Q | Phi coefficient (dichotomous) or Cramér’s V (not restricted to dichotomous)\u003Cbr>p. 403 |\n| Ordinal\u003Cbr>(Rank) | Mann-Whitney\u003Cbr>Test\u003Cbr>p. 396 | Wilcoxon\u003Cbr>signed ranks\u003Cbr>test\u003Cbr>p. 396 | Kruskal\u003Cbr>Wallis H test\u003Cbr>p. 400 | Friedman’s\u003Cbr>test\u003Cbr>p. 400 | Spearman’s rho (or Kendall’stau) pp. 403 |\n| Interval or Ratio (Continuous)* | Independent\u003Cbr>group t test\u003Cbr>pp. 394-395 | Paired\u003Cbr>t test\u003Cbr>p. 396 | ANOVA\u003Cbr>pp. 396-399 | RM\u003Cbr>ANOVA\u003Cbr>pp. 400 | Pearson’s r\u003Cbr>p. 402 |\n|  | Multifactor ANOVA for 2+ independent variables p. 398 |  |  |  |  |\n|  | RM-ANOVA for 2+ groups x 2+ measurements over time p. 424 |  |  |  |  |\n\n*For distributions that are markedly nonnormal or samples that are small, the nonparametric tests in the row above (for ordinal measures) may be needed.  \nSouth Asian Edition of  \nNURSING RESEARCH  \nGenerating and Assessing Evidence for Nursing Practice  \n11th Edition  \nDenise F.
