Area of study in research generally delimit that particular area of interest which is to be examined in order to achieve the objectives of the research.
Generally, the area of study defines the target segment which can be a location. When the area of interest is known, it serves as a guide to the population of study.
Population of study in simpler terms refers to the whole body of items, objects or people that fall within the geographical area in which the researcher seeks to investigate for his study. A researcher may choose to study the entire population when the following conditions are met.
1. The population size is small.
2. When the research has no time bound or there's enough time for the research to be carried out.
3. When there are adequate resources available such as money, materials and human.
4. When the aim of the research is to take census of the population.
There are different types of population a researcher can work with. Notable amongs them are the following;
1. Finite Population: A complete set of items or objects that are finite. Examples are employees of a company, citizens of Ghana.
2. Infinite Population. A theoretical construct that is potentially infinite in size thus counting the units in the population is not possible. Example, germs in a patient's body.
3. Homogeneous population: Population that consists of discrete elements that have common property with very little variation such as same age, s*x, level of education and rank in a job.
4. Heterogeneous population: Population with different categories of participants or elements that have uncommon characteristics e.g. children in all classes in a school or all categories of workers in an organization (lecturers, accountants, clerks, secretaries, managers, directors and artisans).
When researchers have limited time to work on a large population and the available resources aren't enough, there's therefore the need to work with a sample.
