Select the non-probability sampling techniques. Choose the correct answer from the options given below.
- 1. Systematic sampling
- 2. Simple random sampling
- 3. Snowball sampling
- 4. Purposive sampling
A1, 2 only
B3, 4 only ✓ Correct
C1, 3, 4 only
D1, 2, 3 only
Correct answer: (B) 3, 4 only — The non-probability techniques are 3 and 4, so that is the answer.
Explanation
★The non-probability techniques are 3 and 4, so that is the answer.
★Snowball sampling recruits through referrals, a non-probability method.
★Purposive sampling selects cases deliberately, also non-probability.
★Systematic and simple random sampling are probability methods.
★So they use known selection probabilities.
★Hence 3 and 4 only is correct.
