RESEARCH METHODOLOGY

Detailed explanation-1: -Most social science, business, and agricultural surveys rely on random sampling techniques for the selection of survey participants or sample units, where the sample units may be persons, establishments, land points, or other units for analysis.

Detailed explanation-2: -Disadvantages. If the sampling frame is large random sampling may be impractical. A complete list of the population may not be available. Minority subgroups within the population may not be present in sample.

Detailed explanation-3: -The use of simple random sampling removes all hints of bias-or at least it should. Because individuals who make up the subset of the larger group are chosen at random, each individual in the large population set has the same probability of being selected.

Detailed explanation-4: -Simple random sampling is a type of probability sampling in which the researcher randomly selects a subset of participants from a population. Each member of the population has an equal chance of being selected.
