We need this to figure out how much “space” we need to divide into groups. A histogram divides up the range of possible values into buckets or bins, places each observation into the relevant bin and then shows how many observations are in each bin. When considering working with classes instead, you should consider instead this histogram maker, or even this frequency polygon maker, which will work with interval classes that will give a better perspective of the distribution the sample data was drawn from.
