Find the Mode from this chart? Mode is the most common thing in the data chart. I have no idea how to figure this question out.... Solution The mode is indeed the number which appears most frequently in the chart. However, it is possible to have more than one mode. If a set of data is bimodal, there are two modes. If it is trimodal, it has three modes. Typically, anything that has more than two modes is referred to as multimodal. None of the numbers above repeat, as it is easy to see. Thus, each number appears exactly once, which means that each number that appears once must be a mode of the data set. So the above set of data is multimodal, and each given number is a mode, for a total of 11 modes..
