PSYC 2017 Chapter Notes - Chapter 9: Effect Size, Institutional Animal Care And Use Committee, Pilot Experiment
Document Summary
Chapter 9: procedure for conducting an experiment: institutional approval, conducting a study that uses nonhuman animals as research participants, must receive approval from the institutional animal care and use committee (iacuc) Review protocols to ensure that participants will provide informed consent for participation in the study and that the procedures will not harm the participants. Power: the probability of rejecting a false-null hypothesis. We want power to be high; we want to have a power of at least 0. 80 (correctly reject a false-null 80% of the time) As the number of participants within a study increases, the ability of our statistical tests to detect an effect of the iv increases; that is, the power of the statistical test increases. As sample size increases, the cost in terms of both time and money increases. Involves the consideration not only of when the researcher has time available but also of the type of participants being used: consent to participate.
