A distribution with more than one mode is called what?

A distribution with more than one mode is called what?

• A. Bi-modal distribution
• B. Normal distribution
• C. Uniform distribution
• D. Skewed distribution

Answer: (A)

The key idea is about the number of peaks, or modes, in a distribution. The mode is the value that occurs most often, and a distribution with more than one peak has multiple modes. When there are exactly two peaks, we call it bimodal. The normal distribution has a single peak, so it’s unimodal. A uniform distribution has no single peak because all values occur with equal frequency. A skewed distribution has one peak but is not symmetric. Therefore, the distribution with two peaks, or more generally multiple peaks, is best described as bimodal.
