PSYA01H3 Chapter Notes - Chapter 2: Confounding, Scientific Method, Central Tendency
Document Summary
The three types of scientific research include: naturalistic observations involve observing people or animals in their natural environments with as little disturbance as possible. Problem: you do not know what is causing the behaviors there are much too many variables: experiments use active manipulation to get an understanding of how variables effect behavior. 1)identify the problem and for a cause-effect hypotheses. 4)evaluate the hypothesis on the basis of the obtained data. Through naturalistic observations we may use the chain mail example to for the hypothesis that sharks truly don"t like electrical conductors. It is not humans that they hate or blood that they like but the metal they are wearing which tends to blind sharks. The researcher exposes the variables in different orders to two groups so that the effect of each variable can truly be determined. Perform the experiment: reliability is not to be confused with variability. Ethics: research ethics boards (reb) are always required.
