A bimodal distribution is a probability distribution with two different modes. For example, exam grades can be bimodal when the students can be classified into one of two groups: either they understand the material or they understand less than half the material. The grades of each group may be normally distributed. Let's call these two groups A (those who understand the material) and B (those who understand less than half the material). 1>A distribution is noticably bimodal if the means of each distribution are separated by at least one standard deviation.
