With respect to a research paper, explain the difference between the population and sample. What is meant by the representativeness of a sample? How will you ensure representativeness of your sample?

Solution

Population means a group of observations having something in common. Say, all the people of America. Sample means a smaller group of observations taken out of the population.

Representativeness of a sample means its accuracy in reflecting the population. To ensure representativeness of a sample, we can take a larger sample, or take a sample by carefully taking into account the key variables and observations that are being studied.
