Document Summary
Five characteristics of quality scientific research: based on measurements that are objective, valid, and reliable, it can be generalized, reduces bias, made public, can be replicated. Foundation of scientific methodology is the use of objective measurements: the measure of an entity or behavior that, within an allowed margin of error, is consistent across instruments and observers. Operational definitions: are 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: when it provides consistent and stable answers across multiple observations and points in time. Refers to the degree to which one set of results can be applied to other situations, individuals, or events. One way to increase the possibility that research results will generalize is to study a large group of participants.
