A frequency curve in which there are two modes, resulting in a "dip" in the middle of the graph. The mean and median fall between the two modes
Dealing with two modalities

Having two modes, which are the most frequently occurring number in a list
pertaining to a set of data values in which there are two modes (trimodal refers to three modes, etc.); see mode
A particle size distribution exhibiting two mode sizes. Although such a powder can result from mixing two different particle size distributions, some powder production techniques naturally produce this distribution. Its main advantage is in producing a higher solids loading in the PIM feedstock. It is common to use trimodal mixtures in ceramic PIM.
