Answer:
Yes, I agree with the statement that non-sampling errors are more serious than sampling errors because a sampling error can be minimized by taking a larger sample. It is difficult to minimize non-sampling error, even by taking a large sample. Even a Census can contain nonsampling errors.
Some of the non-sampling errors are:
1. Errors in Data Acquisition:
This type of error arises from the recording of incorrect responses. Suppose, the teacher asks the students to measure the length of the teacher’s table in the classroom. The measurement by the students may differ. The differences may occur due to differences in measuring tape, carelessness of the students, etc.
2. Non-Response Errors:
Non-response occurs if an interviewer is unable to contact a person listed in the sample or a person from the sample refuses to respond. In this case, the sample observation may not be representative.
3. Sampling Bias:
Sampling bias occurs when the sampling plan is such that some members of the target population could riot and possibly be included in the sample.
