PSYC 2400 Lecture Notes - Lecture 2: Naturalistic Observation, External Validity, Structured Interview
Document Summary
Reliability- the degree to which independent measurements of a given behavior are consistent. Validity- the degree to which a test measures what is intended to measure. Internal validity- can effects be attributed to variables that the researcher intentionally manipulated. A research procedure in which all participants are asked to answer the same questions. A procedure in which questions are adjusted in accord with the answers the interviewee provides. Examination of ongoing behavior in an environment not controlled by the researcher. A method that involves presenting an identical situation to each child and recording the child"s behavior (nat observation) pros: illuminate social interaction process/ cons: not designed to test cause and effect. Interviews and observations are forms of correlational designs- studies intended to indicate how variable are related to each other. These studies yield a correlation coefficient- a stat that indicates the direction and strength of correlation. Strength: measured between 0 (no relationship) and 1 (perfectly predictive)
