The mode is one of several measures of central tendency that statisticians use to indicate the point (or points) on the scale of measures where the population is centered. It is the score in the population that occurs most frequently. Please notice that the mode is not the frequency of the most numerous score. It is the value of that score itself.
Also notice that if there are two (or more) different scores that occur with equal frequency and that frequency is higher than the frequency of any of the other scores, the population is described as multi-modal
