Document Summary

As soon as people observe an event, their knowledge of it becomes subjective (their knowledge of the event is shaped by prior beliefs, expectations, experiences, and even their mood) 5. it is based on measurements that are reliable and objective it can be generalized it uses techniques that reduce bias it is made public it can be replicated. Objective measurements: the measure of an entity or behaviour that, within an allowed margin of error, is consistent across instruments and observers. Operational definitions: statements that describe the procedures (or operations) and specific measures that are used to record observations (ex. how would you define personality, shyness, or cognitive ability?) Validity: the degree in which an instrument or procedure actually measures what it claims to measure. Reliability: when a measure provides consistent and stable answers across multiple observations and points in time. Alternate forms reliability: whether different forms of the same test produce the same results.
