Concept of Sample – In its most common sense, methodology is the study of research methods. However, the term can also refer to the methods themselves or to the philosophical discussion of associated background assumptions. A method is a structured procedure for bringing about a certain goal, like acquiring knowledge or verifying knowledge claims. This normally involves various steps, like choosing a sample, collecting data from this sample, and interpreting the data. The study of methods concerns a detailed description and analysis of these processes. It includes evaluative aspects by comparing different methods.
In this way, their benefits and drawbacks are evaluated, as well as the research goals for which they may be used. These descriptions and evaluations are predicated on philosophical background assumptions; examples include how to conceptualize the phenomena under study and what constitutes evidence in favor of or against them. In its broadest sense, methodology encompasses the discussion of these more abstract issues.
Concept of Sample
Definition of Sample
A sample is a part of the population about which information is actually obtained with a view to studying the population characteristics. A sample should therefore be representative of the population. The representativeness of the sample is ensured by random selection of sample units.
(Ref by- Rashid, Khabir, Hyder/5h/111)
The subgroup of population selected for an investigation to get an idea about the population is termed as sample.

Definition of Sample Unit:
Each number of population from which we collect data is called sample unit.
(Ref by- Rashid, Khabir, Hyder/4/111)
Each member of the sample is the sampling unit or unit of analysis.
(Ref by- Sadeka Tahera Khanom/Research Methodology/37)
Definition of Sampling Frame:
All listed units or items constituting the study population are called the sampling frame.
(Ref by- Sadeka Tahera Khanom/Research Methodology/2nd/37)
The list of all sampling unit in the population survey is called sampling frame.
