Answer
A population consists of all elements, including individuals, items or objects whose characteristics are being studied.
A sample is a portion of the population selected for study.
A representative sample is a sample that represents the characteristics of the population as closely as possible.
In a sampling with replacement, the element selected from the population can be put back in the population before we select the next element.
In sampling without replacement, the element selected is not replaced in the population.
