Match List-I with List-II
| List-I | List-II | ||
| [Types of Probability Sampling] | [Characteristic] | ||
| (A) | Simple random sampling | (I) | Every member of the population is arranged in a particular order. The first member is selected at random and then the remaining members are selected at regular intervals. |
| (B) | Systematic sampling | (II) | The population is divided into subgroups and each subgroup has similar characteristics of the whole population. |
| (C) | Stratified sampling | (III) | Every member of the population has an equal chance of being selected. |
| (D) | Cluster Sampling | (IV) | The population is divided into subgroups based on the relevant characteristics |
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) Simple random sampling
This matches (III) Every member of the population has an equal chance of being selected.
(B) Systematic sampling
This matches (I) The members are arranged in order, the first is chosen at random and the rest at regular intervals.
(C) Stratified sampling
This matches (IV) The population is divided into subgroups (strata) based on the relevant characteristics, and a sample is drawn from each stratum.
(D) Cluster Sampling
This matches (II) The population is divided into subgroups (clusters) each similar to the whole population, and whole clusters are selected.
So the matching is (A)-(III), (B)-(I), (C)-(IV), (D)-(II).
Tip: Strata differ from one another (members within a stratum are alike); clusters are alike (each is a small copy of the population). This is what separates (C) from (D).
