Document Summary
Associative - relationship between variables; but not causation; not a definitive; we know they"re related but nothing more; correlational. Causal - cause-and-effect relationship between variables; this causes this; we have definitive data. Group differences - naturally occurring sometimes (like a patient showing up in the hospital that week while you"re doing the study); or researcher controlled (the researcher determines the group differences; recruits specific subjects; putting them in different groups) Simple - not saying anything about a relationship; relationship is not mentioned at all: simple vs. complex, nondirectional vs. directional. Nondirectional - relationship exists between variables, but hypothesis does not predict nature of relationship; i know there"s a relationship but i don"t predict it in my hypothesis. Directional - nature (positive or negative) of interaction between two or more variables is stated; These are developed from a theoretical framework, literature, or clinical practice: null vs. research.
