Question

Quizplus · Accepted Answer

The distribution of scores in most psychological research studies are unimodal, meaning they have one peak or mode. This is because scores tend to cluster around a central tendency, such as the mean or median. Bimodal and multimodal distributions are rare in psychological research and usually indicate multiple distinct groups or subpopulations within the sample. Rectangular distributions are also rare and occur when all scores have an equal frequency.
