Which of the following methods give better results and why?






Sample Method gives better results than the Census Method due to the following reasons.

1. Accuracy- Although census method provides more accurate and reliable results as compared to the sample method but in the sample method the errors can be easily located and rectified in the sampling methods due to the smaller number of items. Therefore, despite sample method providing lesser reliable results (as not all units are studied) yet the sample method is efficient in a sense that errors committed can be easily located.

2. Less Time and Energy Consuming- The Sample Method involves study of fewer items of the universe. So, this method not only saves time but also energy of the investigator.

3. Cost Efficient- The cost of approaching each individual unit for interrogation and collection of data is comparatively lower due to small size of sample.

4. Lesser Non-sampling Errors- The probability of Non-sampling Errors is also low as the sample size is smaller as compared to that of the Census Method.

5. More Efficient- As the sample size is smalle, so the small teams of enumerators can be formed. These small teams can easily be well trained and supervised. Consequently, the team can work more efficiently than the team engaged in the Census Method.
