Step 2 form a hypothesis about the relationship between variables: hypothesis: prediction to be tested in a study, variable: an aspect of a study that can change, either purposely changed(manipulated) or measured in a study. Step 3: test the hypothesis by collecting data using operational definitions of variables: operational definition: definition of a variable that specifies how it is measured/manipulated in a particular experiment. Step 4: formulate a theory( hypothesis and theory is different: set of principles that explain a set of observations. Step 5: test the theory by generating new hypothesis. 3 major types of research: descriptive research, describes characteristics of a phenomenon of a group, studying one person/group in depth, examine exceptional, rare cases, e. g brain-damaged patients.
