Document Summary

Operational definitions definition based on how something is measured. Principle of falsifiability you have to be proved wrong. Confirmation bias tend to search for/interpret new information in a way that confirms perceptions and avoids information and interpretations that contradict prior beliefs. Be open to ideas/ free flow of ideas and full disclosure of the procedures used in a study. Confidentiality: the information you provided is confidential. Risk-benefit ratio: minimize risk and maximize benefit. Special populations (children, mentally retarded, psychosis, prisoners) E. g. people who are under 18 must be protected. There is a guardian to speak to. Don"t want to tell people what they are doing exactly. Maybe people are biased to answer questions. Special populations (people with less power) need extra protection. Proposed cause of change in the dependent variable. E. g. gender (cannot manipulate), go through puberty or not. Outcome variable: what we expect to happen.
