The prefix bi means two so a graph with two peaks is called bimodal. But we can group the values to see if one group has more than the others. Any bump in the data is a mode so bimodal distribution has two distinct clear modes.
Bimodal distribution a statistical pattern in which the frequencies of values in a sample have two distinct peaks even though parts of the distribution may overlap.
These appear as distinct peaks local maxima in the probability density function as shown in Figures 1 and 2. Bimodal distribution a statistical pattern in which the frequencies of values in a sample have two distinct peaks even though parts of the distribution may overlap. The prefix bi means two so a graph with two peaks is called bimodal. First if the data values seem to pile up into a single mound we say the distribution is unimodal.
