Strives for objectivity - assumes that certain facts about the world can be observed and tested independently from the individual who describes them. Subjective - the knowledge of the event is shaped by prior beliefs, expectations, experiences, and even their mood. Objective measurements: the measure of an entity or behavior within an allowed margin of error(little error), in consistent across instruments and observers. Variable - the object, concept, or event being measured - perceptual processes, learning and memory, interaction with others, etc. Samples of blood or saliva - enzymes, hormones, other biological variables. Operational definitions - statements that describe the procedures and specific measures that are used to record observations. Validity - the degree to which an instrument or procedure actually measures what it claims to measure. Reliability - provides consistent and stable answers across observations and points. Score or rate a behavior response: generalizability of results. Generalizability - the results can be applied to other situations, individuals, or events.
