Which term describes a distribution where the two sides are not equal?

• A. Symmetrical distribution
• B. Normal distribution
• C. Uniform distribution
• D. Asymmetrical distribution

Answer: (D)

Describing a distribution where the left and right sides around the center don’t mirror each other points to asymmetry. When one tail is longer or the peak sits off-center, the two halves aren’t equal, so we call that asymmetrical (or skewed) distribution. This contrasts with symmetric shapes like the normal distribution, where left and right sides match, and with a uniform distribution that spreads evenly across values. So the term for unequal sides is asymmetrical distribution.
