Document Summary
As soon as people observe an event, their interpretation becomes subjective: knowledge is shaped by prior beliefs, expectations, experiences, even their mood. Five characteristics of quality scientific research: quality scientific research meets the following. It is based on measurements that are objective, valid, and reliable. Scientific measurement: objectivity, reliability, and validity: objective measurement: the measure of an entity or behaviour that, within an allowed margin of error, is consistent across instruments and observers. Test-retest reliability: examines whether scores on a given measure of behaviour are consistent across test sessions. Alternate-forms reliability: examines whether different forms of the same test produce the same results. Inter-rater reliability: raters agree on the measurements that were taken. Hawthorne effect: a behaviour change that occurs as a result of being. Sharing the results: peer review: a process in which papers submitted for publication in scholarly journals are read and critiqued by experts in the specific field of study.
