PSYA01H3 Chapter Notes - Chapter 2.1: Falsifiability, Demand Characteristics, Ecological Validity
Document Summary
5 characteristics of quality scientific research: based on measurements that are objective, valid, and reliable, can be generalized, uses techniques that reduce bias, made public, can be replicated, scientific measurement: objectivity, reliability, and validity. Objective measurements: measure of an entity or behaviour that, within an allowed margin of error, is consistent across instruments and observers: foundation of scientific methodology. Variable: object, concept, or event being measured. Operational definitions: statements that describe the procedures (or operations) and specific measures that are used to record observations. Search through the existing research literature before you make any decisions. Validity: the degree to which an instrument or procedure actually measures what it claims to measure. Inter-rater reliability: raters agree on the measurements that were taken. Not limited to a small group of people; ideal to relate to other groups and situations (ideal to be generalizable: generalizability of results.
