4. Purposive sampling
Show Hint
Probability sampling ensures randomization and reduces selection bias, making it ideal for statistical generalizations.

Verified By Collegedunia
The Correct Option is B
Solution and Explanation
Probability sampling methods are those in which each unit in the population has a known and non-zero chance of being selected. These include:
- Simple random sampling: Every individual has an equal probability of being chosen.
- Systematic random sampling: Selection occurs at regular intervals from a list.
- Stratified random sampling: The population is divided into subgroups (strata), and random samples are taken from each stratum.
Purposive sampling is a non-probability sampling method where participants are selected based on specific characteristics or judgment, not randomization.
Thus, the correct answer is (A), (B), and (C) only.
