Generating Frequencies
Many times, the most meaningful aspect of a data set is its
distribution. Frequencies and frequency distributions are a common
method for analyzing the distribution of a set of data.
Frequencies are created by dividing an interval (often that betvceen the
largest datum and the smallest) into an arbitrary number of equal
subintervals, or bins, the number of which is suggested by the data
and the precision with which one wants to study the distribution. The
diagram below illustrates this.
