The Mode is the value that occurs with the greatest frequency. It is quite often the case that the mode occurs near the middle of the population. Hoever, there simply may not be a mode at all. In the case of our sphere population, we have a bimodal histogram, with the values 4 and 8 both occuring twice.
Mode= 4, 8
While the Mode, the Mean, and the Median provides us with valuable information concerning the range of the constituents in a given population, these measurements do little to indicate the dispersion of the members of a population. Measures of Dispersion are methods with which we can analyze the spread of data. Let us begin with The Range.
