Document Summary

Disadvantages: attrition, harder to conduct, time shifts (validity) An approach in which the influence of the independent variable on the dependent variable is determined with random select. Variable that hypothesize causes changes in the dv. Measured by the researcher & its changes are used to support (or refute) hypotheses. We have to infer personality based on observable behaviour. We can obtain information about personality from collecting data based on what people say about their own personality (s-data) What other people say about someone else s personality (i-data) How the person if doing in life (l-data) Involves asking the person directly to tell you about their own personality. Ex. numerical ratings in response to questions/statements (closed-ended) Involves asking someone who knows the target person to tell you about the target s personality. Can vary in terms of how well informant knows target. Can use multiple informants & aggregate i-data (informant-report data) advantages.
