Document Summary
The experimental method: when conducting experiments in psychology, there is almost always a trade- off between internal and external validity. Having enough control over the situation to ensure that no extraneous variables are influencing the results. Ensuring the results can be generalized to everyday life. To get around this - use mixed methods: replication: repeating a study, often with different subject populations, or in different settings, is the ultimate test of an experiment"s external validity, science has no value without replication. How will we know unless we repeat the study: bystander study. Another participant (actually a tape-recording of an actor) had an epileptic seizure. If participants believed they were the only ones present: 85% helped. If participants believed that they were in a group of 5 participants: 31% helped. Research consideration: internal validity: keeping everything the exact same except for the iv, random assignment: equal proportion of individuals randomly assigned to.
