Differentiate broadly between a population and a sample. ?

A population refers to the entire group of individuals or items that are of interest to a researcher and to which the researcher wants to generalize their findings. A sample, on the other hand, is a subset of the population that is selected for study in order to make inferences about the population as a whole.

In other words, a population includes all members of a specified group, while a sample is a smaller group selected from the population to represent the larger group. The goal of sampling is to select a sample that is representative of the population so that the findings from the sample can be generalized to the population.
