Document Summary
Repetition of a study to see if earlier results stay the same. Combination of results of many studies on the same question to measure consistency. When a sample is not representative of the population. Expectations lead to an experience that is not really happening. Social desirability bias: giving socially approved answers. Response set: responding to questions in an unrelated way. Neither subjects or researchers know which subjects are in experiment or control group. Studies which data collection is one using the web. Consists of personal stories about speci c incidents and experiences. The use of mathematics to organize, summarize, and interpret numerical data.
