The are some limitations for stat.
Only under a specific set of conditions, the projection of production, price of a commodity and sales for future is possible. In case the rules for random sampling are not followed properly, The decision which we make based on those samples will never be correct.
Suppose, the management of a company does not follow the rules of random sampling, the future projection made by the management of the company will go wrong. The company may have to face huge loss.
