Quizplus · Accepted Answer

Sampling bias occurs when the sample of participants in a study is not representative of the population being studied, and one group may be overrepresented. The other choices (response bias, experimenter effects, and interviewer bias) refer to different types of biases that can affect the validity of a study, but they do not necessarily involve overrepresentation of a particular group in the sample.
