Explanation:
Detailed explanation-1: -Studies are conducted on samples because it is usually impossible to study the entire population. Conclusions drawn from samples are intended to be generalized to the population, and sometimes to the future as well. The sample must therefore be representative of the population.
Detailed explanation-2: -Reasons for sampling Necessity: Sometimes it’s simply not possible to study the whole population due to its size or inaccessibility. Practicality: It’s easier and more efficient to collect data from a sample. Cost-effectiveness: There are fewer participant, laboratory, equipment, and researcher costs involved.
