ANOVA test - ANSWER-analysis of variance used in research studies where there are two or more
groups to compare

nominal data - ANSWER-measured as a frequency or percentage. the mean cannot be calculated

Pearsons correlation - ANSWER-determines the extent to which a change in one variable tends to be
associated with a change in another



t-test - ANSWER-compare whether two groups have different average values



confounding variable - ANSWER-obscures the effect of another variable



dichotomous variable - ANSWER-binary variable

Chi-square test - ANSWER-determine if an association exists between two categorical variables



F-Test - ANSWER-test if two population variances are equal. If the variances are equal the ratio will
be 1

ordinal data - ANSWER-measured as a frequency and the mean can be calculated



parametric tests - ANSWER-based on probability distributions



nonparametric tests - ANSWER-Used when data are not normally distributed or do not meet other
criteria for parametric tests (e.g., discrete data). May also be used for continuous data that do not
meet the assumptions of the t-test or ANOVA




interval data - ANSWER-units of equal size. there is no zero point



multivariate regression analyses - ANSWER-used to analyze and adjust risk. Contrasts each measured
factor to the patient's risk of a particular outcome
