1. Nature of enquiry – The limited enquiry is conducted as only a few units of the population are studied.
2. Economy – Less Time, Money, and Labour Relatively less money, time, and labour are required.
3. Suitability – It is more suitable if the population is homogeneous in nature.
4. Reliability and Accuracy – The results of the sampling method are less reliable because a high degree of accuracy is not achieved.
5. Organisation and Supervision – The sampling method is comparatively easy to organise and supervise.
6. Verification – Under this method, the results can be tested by taking out another small sample.
7. Nature of method – The sampling method is a new and practicable method. It is a scientific method.
