Document Summary
Fact: can be verified and is established with overwhelming evidence (opposite of myth: opinion/value/belief: not possible to prove or disprove through scientific evidence. This is a research/evidence based course: anecdotes are for explanatory purposes, not evidence. Sample selection: population, all individuals in a group that share a particular characteristic, often impossible to find and survey all individuals in the group. Sample: a group of individuals who represent the entire population. Methods: surveys: used to systematically collect information, predetermined questions, questionnaires. Systematic observation of people in their natural surroundings: participate observers, researchers interact naturally, but do not reveal their identities, non participant researchers. Secondary analysis: use of data that was collected by someone else, historical documents, public records, official statistics. Examinations of cause and effect relationships under controlled conditions. Individuals assigned by experimenter into one of two or more groups: outcomes observed - cause and effect can be determined"
