Which Test? Flashcards
Which test do you use with one group if your outcome variable is continuous and parametric?
One sample t-test
Which test do you use with two independent groups if your outcome variable is continuous and parametric?
2 sample t-test
or linear regression
Which test do you use with one group if your outcome variable is continuous and non parametric?
Sign test or signed rank test
Which test do you use with two independent groups if your outcome variable is continuous and non parametric?
Mann Whitney U test
Which test do you use with a paired sample if your outcome variable is continuous and parametric?
Paired t-test if at two time points
Bland Altman if two alternative measurement (for agreement)
Which test do you use with one group if your outcome variable is binary?
Chi squared
Which test do you use if you have 2 independent groups and your outcome is binary?
Chi squared
Fisher’s exact if one of the cells in the table has an expected count of less than 5
Logistic regression
Which test do you use if you have more than 2 samples and you routcome variable is continuous and parametric?
ANOVA
linear regression
Which test do you use if you have more than 2 samples and you outcome variable is continuous and non parametric?
Kruskal Wallis test
Which test do you use to test correlation between two continuous variables
Pearson
Linear regression
What is the non parametric equivalent to pearson?
Spearman’s rank test
linear regression
What tests are used to asses agreement between two assessments?
Kappa if categorical
McNemar’s if proportions are paired
What tests can be used if you have more than 2 samples and a binary outcome?
Chi squared, fisher’s exact or logistic regression
What is the non parametric equivalent of the 2 sample t-test?
