RESEARCH METHODOLOGY

Detailed explanation-1: -*A population consists of all subjects that are being studied. *A sample is a group of subjects selected from a population.

Detailed explanation-2: -In statistics, a population is the pool of individuals from which a statistical sample is drawn for a study. Thus, any selection of individuals grouped by a common feature can be said to be a population. A sample may also refer to a statistically significant portion of a population, not an entire population.

Detailed explanation-3: -A group of subjects selected from the population under study is called a sample. Observations drawn from a representative sample can allow researchers to draw inferences about the population as a whole.

Detailed explanation-4: -Inferential statistics consists of generalizing from samples to populations, performing estimations and hypothesis tests, determining relationships among variables, and making predictions.
