Document Summary
Research setting: laboratory research done in a controlled environment, can remove confounding factors, drawbacks: Participants know that they are being studied. Can cause the participants to behave unnaturally. Need to be able to get varied participants to the lab. Cannot examine all behaviors in a lab: natural setting research done in an environment where the behavior occurs naturally, conducted at sporting events, child care facilities, work places, shopping mall, and schools. Median: measure of dispersion describes how much a score in a sample differ from one another; this measure tells us the variability (differences) in the scores: In psychological research the standard is that if the odds are 5 out of 100 (or. 0. 05) or less that the differences are due to chance, and the results are considered statistically significant or confidence level of . 05. Statistically significant that the differences observed between two groups are large enough that it is highly unlikely that those differences are due to chance.
