Question
With the help of suitable example, explain conversion of an Inclusive Distribution into Exclusive Distribution.
✓

Answer

In inclusive distribution, there is a gap or discontinuity between the upper class limit and lower class limit of the next class. To maintain the continuity, the class intervals are adjusted and an exclusive distribution is obtained. The adjustment is done with the help of following steps.
Step 1: The difference between the lower limit of second class and upper class limit of first class is obtained.
Step 2: The difference obtained is divided by 2.
Step 3: Value obtained in Step 2, is subtracted from lower limit of all the classes and added to the upper limit of all the classes.
Consider the given distribution.
Income of 350 Employees of a Company
Income (₹) Number of Employees
800-899 50
900-999 100
1000-1099 200
Total 350
Step 1: Difference between lower class limit of lind group and upper class limit of Ist group is computed which is 1 (900-899).
Step 2: This difference is divided by 2 and we get 0.5 $(\frac{1}{2}=0.5)$
Step 3: 0.5 will be subtracted from the lower class limit of each group and added to the upper class limit of each group.
