which of the following methods gives better results and why? (a) census (b) sample
Answers
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.
Answer:
The correct answer of this question is option a , census method.
Explanation:
Census method of data collection is always better than the sample method because;
1) The results obtained from census method is more accurate.
2) The census method is less time consuming.
3) Less amount of the manual efforts are necessary for the census method.
4) Census method is lot more easier than the sample method.
And many more.
