Referential value in a series of data to the most common, most often occurring value. In a frequency distribution graph, the peak represents the mode. The mode of the series 1, 2, 2, 3, 4, 4, 4, 5, 5, 6 is 4 because it occurs most often. There may or may not be a mode, or two modes, known as a bimodal series, or even more modes, known as a multimodal series.
