Explanation Given info: The table shows the frequency distribution for the blood platelet count of males with the corresponding frequencies. Calculation: Class width : The class width is the distance between two successive lower limits of class intervals. The formula for class width is as follows: Class width = Second lower class limit − First lower class limit Substitute 100 for “Second lower class limit” and 0 for “First lower class limit” Class width = 100 − 0 = 100 Thus, the class width is 100. Class midpoints : The midpoints of the classes are termed as class midpoints. Each class midpoint is the average of the upper and the lower limits of a class interval. The formula for midpoint is, Class midpoint = Lower class limit + Upper class limit 2 Substitute 0 for the lower class limit and 99 for the upper class limit Class midpoint = 0 + 99 2 = 49.5 Similarly, the class midpoints for remaining class intervals are shown in Table (1). Blood Platelet Count of Males Class midpoint 0-99 0 + 99 2 = 49.5 100-199 100 + 199 2 = 149.5 200-299 200 + 299 2 = 249
