SOP 3004 Chapter Notes - Chapter 1: Random Assignment, Demand Characteristics
Document Summary
Random sample - every person in the population being studied has an equal chance of inclusion in the survey. Theory - an integrated set of principles used to explain and predict observed events. Experiments have two major advantages over correlational studies: random assignment and control. Experimental research - studies that seek clues to cause-effect relationships by manipulating one or more factors while controlling others. Random assignment helps to create equivalent groups. Values - personal convictions about what is right and how people should behave. People often construct their social world to explain behaviour and make it seem orderly, predictable and controllable. Demand characteristics - when subjects receive experimenter cues that guide their behaviour and suggest how to act. Framing - the way a question is posed. Time-lagged correlations reveal the sequence of events. Random assignment - when participants in an experiment have an equal chance of being assigned any condition within the study.
