Explanation:
A sample study in Statistics refers to the selection of some specified or particular observations or items from the entire set of the target population or the universe in any statistical study.Hence,in the case of a considerably large target population or universe size,it is practical or logical to use the sample study to save time,effort and financial resources of the researcher.The researcher can emphasize on some particular sections or features of the target population which can represent the true characteristics or the overall set of the population and hence,accurate population estimates can be obtained.Therefore,larger the population size,larger and more representative the sample has to be in order to attain accurate statistical results or outcome about the population.
