PSYA01H3 Lecture Notes - Lecture 7: Institutional Review Board, External Validity, Operational Definition
Document Summary
Venting frustration on another group of people. If we can manipulate self esteem, and if we can measure prejudice. Confound - 2 variables that are different. Representative groups - similar to each other and not systematic. Define things in a way to operate, measure stuff. You have to make operational definition in order to do an experiment. Random selection - if a bias is in, if you repeat it it shouldnt come in again. Give research to at least 3 different researchers studying in the same field to give feedback. External validity - do i think the experiment really maps onto the concepts it is intended to be studying. The role of replication and checks (checks if it supports your hypothesis. Cultural validity - are these findings only applicable to some specific group of humans. Manipulation checks - check if you"re manipulation matches your assumptions. All research goes before an institutional review board (irb) for approval.
