Given below are two statements : Statement I : In probability sampling, it is not necessary that all the members of population have an equal opportunity to be the part of the sample. Statement II : Non probability sampling method is not a fixed or predefined selection process. In the light of the above statements, choose the correct answer from the options given below :
Statement I is false but Statement II is true
To evaluate the given statements about sampling methods, we need to understand the concepts of probability and non-probability sampling.
- Probability Sampling: In probability sampling, every member of the population has a known, non-zero chance of being selected. This is inherent to its definition since it relies on random selection methods. Therefore, Statement I is incorrect because it contradicts the fundamental principle of probability sampling whereby all members do have an equal or known chance of being selected.
- Non-Probability Sampling: In non-probability sampling, there is no random selection process, which means it is not fixed or predefined. Instead, samples are chosen based on subjective judgment rather than random choice. This is commonly used when it is impractical to conduct a random sampling. Statement II correctly describes this method as it emphasizes the lack of a predefined selection process.
Based on the analysis above, the correct interpretation of the statements is:
- Statement I is false because it incorrectly describes probability sampling.
- Statement II is true as it accurately reflects the nature of non-probability sampling.
Hence, the correct answer is "Statement I is false but Statement II is true".
