WebA bell shaped distribution is named because it looks like the shape of a bell when plotted on a graph. These distributions share several important properties: A single peak in the center (i.e., they are unimodal distributions ). Symmetry: If you draw a vertical line down the center of the graph, the left half will mirror the right.
