Correlational research: detecting natural associations
Correlational research The study of the naturally occuring relationships among the variables.
De grote kracht van correlatie onderzoek is dat het voorkomt in real-world gebeurtenissen waarin we factoren zoals ras, sex, and sociale status kunnen examineren, die we niet kunnen manipuleren in een lab-experiment. Het grote nadeel is de meerduidigheid van de resultaten.
Wetend dat twee variabelen tegelijk veranderen stelt ons in staat de ander te voorspellen als we de ene weten; maar correlatie specificeert niet oorzaak en gevolg.
Experimental research Studies that seek clues to cause-effect relationships by manipulating one or more factors (independent variables) while controlling others (holding them constant).
Experimental research: searching for cause and effect
Random assignment The process of assigning participants to the conditions of an experiment such that al persons have the same chance of being in a given condition. (Note the distinction between random assignment in experiments and random sampling in surveys. Random assignment helps us infer cause and effect. Random sampling helps us generalize to a population.)
Mundane realism The degree to which an experiment is superficially similar to everyday situations.
Experimental realism The degree to which an experiment absorbs and involves its participants.
