(3) Determine the class interval (Cl), the width of classes of it may be the difference two succeeding class midpoints (CM). The CM is the average between the limits of a class. For each computation, CI must be a whole number. It can be obtained by the equation CI-R/K-101.5/10-10.15 (4) Take the frequency distribution for each set of data On the basis of this method, the frequency distribution is as follows: Table 8.1.
