ABSTRACT
Population is also sometimes called universe. Population is the totality of elements that have one or more characters in common. In statistical in vestigations, researchers are interested in the study of the characteristics of their population. Therefore, the population concerned is to be specified carefully. Suppose we are interested in a particular character in the popula tion, and we observe that this character takes different values, and these val ues constitute a distribution to that particular character. Our goal is to study the character of our interest and make inferences. Examples of populations are provided here:
1. Number of farmers in a village 2. Number of people in a city 3. Number of trees in a forest 4. Children studying in a school 5. Machines produced in a factory 6. Heights of people in a city or in a country 7. People in a particular age group in a place 8. Population of trees infested with a particular disease 9. Population of patients affected with a disease, e.g., cancer
10. Number of books stocked in a library 11. Suppose we consider that people in a city constitute our population.
