Match List-I with List-II
| List-I | List-II | ||
| (A) | Snowball sampling | (I) | Statistic |
| (B) | A measurable characteristic of a sample | (II) | Parameter |
| (C) | Stratified sampling | (III) | Non-probability sampling |
| (D) | A measurable characteristic of a population | (IV) | Probability sampling |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 3
The correct answer is Option (3) → (A) - (III), (B) - (I), (C) - (IV), (D) - (II)
(A) Snowball sampling
This matches (III) Non-probability sampling.
Existing subjects refer further subjects, so units are not chosen with known probabilities.
(B) A measurable characteristic of a sample
This matches (I) Statistic.
A statistic (such as the sample mean) is computed from a sample.
(C) Stratified sampling
This matches (IV) Probability sampling.
The population is divided into strata and a random sample is drawn from each stratum.
(D) A measurable characteristic of a population
This matches (II) Parameter.
A parameter (such as the population mean) describes the whole population.
So the matching is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
