Document Summary
Being subjective meaning that people"s knowledge of the event is shaped by prior beliefs, expectations, experiences or even that mood. Objectivity assumes that certain facts about the world can be observed and tested independently from the individual who describes them. Based on measurements that are objective, valid and reliable. Objective measurements: the measure of an entity or behavior that within an allowed margin of error, is consistent across instruments and observers. Variable: the object, concept, or event being measured. Operational definitions: statements that describe the procedures(or operations) and specific measures that are used to record observations. Correlational research involves measuring the degree of association between two or more variables. Validity: the degree to which an instrument or procedure actually measures what it claims to measure. Reliability: when it provides consistent and stable answers across multiple observations and points in time. Test-retest reliability examines whether scores on a given measure of behavior are consistent across test sessions.
