In data distributions, which curve is described as having two prominent peaks?

• A. Unimodal Curve
• B. Normal Distribution
• C. Bimodal Curve
• D. Multimodal Curve

Answer: (C)

A distribution with two prominent peaks shows two common or prevailing values in the data, which mathematicians call two modes. This is exactly what a bimodal curve represents—two humps that stand out on the plot. It often arises when the data come from two subgroups or processes blended together, such as scores from two different populations or measurements from two different conditions. The other options don’t fit as well: a unimodal curve has a single peak, representing one main value or cluster; a normal distribution is a specific, symmetric unimodal shape with one peak; and a multimodal curve has three or more peaks.
