Small-scale industries are more “labour intensive” ie they use more labour than the large-scale industries and, therefore generate more employment. But these industries cannot compete with the big industrial firms., it is obvious that the development of small-scale industry requires them to be shielded from the large firms. For this purpose, the production of a number of products was reserved for the small-scale industry, the criterion of the reservation is the ability of these units to manufacture the goods. They were also given concessions such as lower excise duty and bank loans at lower interest rates. Therefore it can be concluded that small-scale industries play a vital role in an economy like India.

Exclusive Method
The classes, by this method, are formed in such a way that the upper-class limit of one class equals the lower class limit of the next class. In this way, the continuity of the data is maintained.

1. The size of items or mid-points of classes is cumulated. The cumulative sum of the items is assumed to be 100. All the different cumulative totals are converted into a percentage.
2. Frequencies are also made cumulative. Last cumulative frequency is considered as 100. Other frequencies except the last are converted into a percentage.
3. Cumulative frequencies are plotted on X-axis while cumulative items are plotted on the Y-axis.
4. We start on X-axis while cumulative items are plotted on the Y-axis
5. 0 on X-axis and 100 on Y-axis are joined by a line. This line is known as the line of equal distribution.
6. We plot the values on X and Y axis in an ordinary way and the plotted points are joined by a curve. It is the curve of actual distribution.
7. The lesser distance between the line of equal distribution and line of actual distribution shows lesser dispersion and so on.
