Document Summary
Subjects/study participants: the people being studied are called subjects/study participants (quantitative) and study participants, informants, key informant (qualitative). The person who conducts the research is the researcher or investigator. Site: a site is the specific location of the research - it could be an entire community, hospitals, homes, or other community settings. Theory: is an explanation of some aspect of reality. Variable: in quantitative studies, concepts are usually called variables. A variable is something that varies (weight, anxiety, fatigue ) - they vary from one person to another, and from time to time. If everyone weighed 150 pou nds, weight would not be a variable, it would be a constant. A variable is any quality of a person, group, or situation that varies or ta kes on different values. Variables are the central building blocks of quantitative studies. Independent variable: the presumed cause is the independent variable. In other words, the independent variable affects how the dependent variable will behave.
