Question

Explain in detail about sampling error

Answer 1

Sampling Error:

Error, which arise in the normal course of investigation or enumeration on account of chance, is called sampling errors, sampling errors are inherent in the method of sampling.

They may arise accidentally without any bias or prejudice.

Sampling Errors arise primarily due to the following reasons:

(a) Faulty selection of the sample instead of correct sample by defective sampling technique.

(b) The investigator substitutes a convenient sample if the original sample is not available while investigation.

(c) In area surveys, while dealing with borderlines it depends upon the investigator whether to include them in the sample or not.

This is known as faulty demarcation of sampling units.
