Mode is a measure of central tendency useful for data at any level of measurement. Like the statistical mean and median, the mode is a way of expressing, in a single number, important information about a random variable or a population.
Mode is the most frequently occurring number in a set of scores or values. In a series of numbers there is frequently more than one mode. Other measures of central tendency are the median and the mean.
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. The mode is not the frequency of the most numerous score. Mode is the value of that score itself.
A mode of a continuous probability distribution is often considered to be any value x at which its probability density function has a locally maximum value, so any peak is a mode. - Zhang, C; Mapes, BE; Soden, BJ (2003). "Bimodality in tropical water vapour".
