Document Summary
Subjective: an individual"s knowledge of an event is shaped by prior beliefs, expectations, experiences, and even their mood. Five characteristics of quality scientific research: it is based on measurements that are objective, valid, and reliable, 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. 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. Validity: the degree to which an instrument or procedure actually measures what it claims to measure. Inter-rater reliability: the raters agree on the measurements that were taken: experiments with clear operational definitions and criteria for raters make it likely that there will be high inter-rater reliability.
