Document Summary
When doing research participants are gathered from a population: samples are gotten from population through probability/no probability sampling. Gathering participants may be easy if you do the haphazard method; nothing wrong with it but results are biased and cannot be generalized to public. To manipulate an independent variable one needs to construct and operational definition of the variable: turning conceptual variables into a set of operations( specific instructions ,stimuli, etc) Before anything is to be done, the researcher has to set the stage: which means provide participants with: Explain why the experiment is being done. To create a psychological state in the participant ( anger, frustration, etc) Stimulate some situations that may occur in the real world. Confederates ( accomplices)- are people who participate in the experiments acting as a participant but is actually there to manipulate or create a particular social situation. Example is asch experiments with the judgement of lines.
