Statement I : The absolute value of the difference between an unbiased estimate and the corresponding population parameter is called sampling error. Statement II : Multi-stage sampling is a restricted non-probability based sampling technique. Indicate the correct code :
Statement I: Sampling Error Analysis
Sampling error is defined as the discrepancy between a sample statistic (such as an unbiased estimate) derived from a sample and the corresponding true value in the population (the population parameter). Statement I accurately describes this concept. Therefore, Statement I is correct.
Statement II: Multi-stage Sampling Type
Multi-stage sampling is a probability-based sampling technique. It involves dividing the population into successive subgroups (stages) and randomly sampling from these subgroups at each stage. This contrasts with non-probability sampling methods, which rely on subjective selection criteria. Statement II incorrectly classifies multi-stage sampling as non-probability based. Therefore, Statement II is incorrect.
Conclusion
Based on the analysis:
- Statement I is correct.
- Statement II is incorrect.
This corresponds to the option where Statement I is correct, and Statement II is incorrect.
