Document Summary
Chapter 2 reading and evaluating scientific research. Objectivity assumes that facts around the world can be observed and tested independently from the individual that describes them (e. g. the scientists) Objective measurements the measure of 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 are statements that describe the procedures/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. Reliability when it provides consistent and stable answers across multiple observations and points in time. Generalizability refers to the degree to which one set of results can be applied to other situations, individuals or events. Multiple factors could have influenced e. g. improvement in grades other than a memory course.
