The distribution of scores in a research study in the behavioral and social sciences is usually unimodal, meaning that there is one clear peak or mode in the distribution. This is because most experimental and survey data will follow a normal distribution, where the majority of scores fall around the mean. Bimodal distributions may occur when there are two distinct groups in the study population, but this is less common in behavioral and social sciences research. Multimodal distributions may occur when there are multiple groups or subpopulations with different characteristics, but again, this is not as common in these fields. Rectangular distributions are rare and indicate a lack of variability in the data.
