The mode is easy to identify, but it does not take all of the scores into account. In some cases, the mode can be very far from the center, as shown in the graph on the left. That mode of 13 is nowhere near the “center” of the data set.

Sometimes you may even have two modes, as in the graph on the right, so which one is the center? We call these distributions, bimodal distributions. As a result, the mode is rarely used as the main measure of central tendency.
