Question

In social research, which sampling method ensures every member of the population has an equal chance of selection?

• A. Stratified Sampling
• B. Simple Random Sampling
• C. Purposive Sampling
• D. Convenience Sampling

Hint:

{Simple Random Sampling} is the most basic probability sampling technique where each unit in the population has an equal chance of being selected.

Answer 1

The Correct Option is B

Step 1: Understanding the Question:
The question asks to identify the sampling technique where every unit in the population has a non-zero, equal probability of being chosen.
Step 2: Detailed Explanation:
Sampling is divided into Probability and Non-Probability sampling.
- Simple Random Sampling (Probability): This is the purest form of probability sampling where each member has an exactly equal chance.
- Stratified Sampling (Probability): The population is divided into strata, and then samples are taken. While it involves chance, the primary definition of "equal chance for every member" without subgroups belongs to Simple Random Sampling.
- Purposive Sampling (Non-Probability): Samples are chosen based on the researcher's judgment.
- Convenience Sampling (Non-Probability): Samples are chosen based on ease of access.
Step 3: Final Answer:
The correct method is Simple Random Sampling.
