Which term describes a frequency distribution that has two dominant values with many cases?

A frequency distribution that has two dominant values is characterized as bimodal. This means that in the dataset, there are two modes, which are the values that appear most frequently. Bimodal distributions indicate the presence of two prevalent groups or peaks within the data set, suggesting that there may be two significant underlying processes or populations represented in the data.

In contrast, a normal distribution is characterized by a single peak (or mode) that is symmetric around the mean. A uniform distribution shows that all values occur with equal frequency, meaning there is no dominant value. A multimodal distribution contains more than two modes, indicating multiple peaks in the data, which would not accurately represent a scenario with just two dominant values. Thus, the term that best describes a distribution with two dominant values is bimodal.
