To solve this question, we need to match the images representing different sampling frames (List-I) with the corresponding sampling procedures (List-II).
- Simple Random Sampling: This is a method where each unit of the population has an equal chance of being selected. Typically, units are selected randomly without any specific pattern.
The image labeled as A is a disperse distribution of selected units, which is characteristic of simple random sampling. - Stratified Random Sampling: In this method, the population is divided into subgroups (strata), and random samples are taken from each stratum.
The image labeled as B shows units divided into separate sections, indicating a stratified random sampling process. - Systematic Sampling: In this method, after selecting a random start, every nth unit is selected from the list.
The image labeled as C shows a pattern of selecting units at regular intervals, which is typical of systematic sampling. - Cluster Sampling: Here, the population is divided into clusters, and entire clusters are randomly selected.
The image labeled as D shows selections concentrated within a specific area, characteristic of cluster sampling.
Based on the descriptions and matches, the correct option is:
A-III (Simple Random Sampling), B-IV (Stratified Random Sampling), C-I (Systematic Sampling), D-II (Cluster Sampling)
