Chi squared
1) Nominal, unrelated (independent groups), test of difference
2) Nominal, (design irrelevant as correlation), correlation (test of association)
Mann Whitney
-Ordinal data, test of difference, unrelated design (independent groups)
Unrelated T- test
-Test of difference, unrelated design (independent groups), interval data
Sign test
-test of difference, related design (matched pairs or repeated measures), nominal data
What determines whether a test is parametric or non-parametric?
-Parametric= interval data (unrelated t test, related t test, pearsons r)
-non parametric= nominal and ordinal data (everything else- chi squared, Mann Whitney, sign test, Wilcoxcon, spearman’s rho)
Wilcoxon test
-Test of difference, related design (matched pairs or repeated measures), ordinal data
Related T test
-Test of difference, related design (matched pairs or repeated measure), interval data
Spearman’s rho
-Test of correlation, Type of design irrelevant as we looking at correlation not experiment, ordinal
Pearsons r
-correlation, design irrelevant, interval data
3 parametric tests?
-Unrelated T test, Related T test, Pearsons r
