Which distribution is defined by having two peaks?

Which distribution is defined by having two peaks?

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

Answer: (B)

The concept being tested is the shape of a distribution and its modes. A distribution with two peaks has two local maxima in its density or frequency plot, meaning there are two prevailing values where data cluster. This is called bimodal. A single peak characterizes unimodal distributions, such as the normal distribution, which is a specific symmetric unimodal curve. Multimodal refers to distributions with more than one peak, which can include two or more peaks but is not specifically limited to two. So the right term for a distribution defined by having two peaks is bimodal.
