Document Summary
Chapter 2 - reading & evaluating scientific research. 5 characteristics of quality scientific research: based on measurements that are objective, valid & reliable, can be generalized, uses techniques that reduce bias, made public, can be replicated. Objective measurements: measure of entity or behaviour that within an allowed margin of error, is consistent across instruments and observers. & specific measures that are used to record specific observations what it claims to measure situations, individuals or events. Validity: degree to which an instrument or procedure actually measures. Reliability: when it provides consistent and stable answers across mult. Generalizability: degree to which one set of results can be applied to other. Population: group that researchers want to generalize about. Random sample: sampling technique, in which every individual of a. Convenience sample: samples of individuals who are the most readily. Ecological validity: meaning that the results of a laboratory study can be.
