How do you describe the shape of distribution?
Understand the Problem
The question is asking for a method or terminology used to describe the characteristics of a statistical distribution, such as its shape, central tendency, dispersion, and skewness.
Answer
The shape of a distribution can be described by its symmetry, number of peaks, skewness, and uniformity.

Answer for screen readers
The shape of a distribution can be described by its symmetry, number of peaks, skewness, and uniformity.
More Information
Symmetry refers to whether the distribution is the same on both sides of a central point. Peaks refer to the highest points in the data set. Skewness indicates if one tail is longer or more stretched out than the other. Uniformity describes if all values are equally likely.
Tips
People often confuse skewness direction - remember, right-skewed means the tail is on the right.
