Instructions
Abstract or concrete qualities, properties, or characteristics of people, things, or situations are
described as variables. Variables are manipulated and/or measured in quantitative research (Grove &
Gray, 2021.) Variables are defined in two way - conceptually and operationally. A conceptual definition is
a broad, abstract definition of a concept. This definition can be found in relevant literature about topics of
interest. For example, pressure injuries are defined as "localized damage to the skin and underlying soft
tissue usually over a bony prominence or related to a medical or other device." (Wound Ostomy
Continence Nursing Society, 2016). As defined here, there is no way to determine change or outcomes
in conceptual definitions. So, we operationalize the variables. Instruments and tools are developed to
make the concepts measurable by assigning numbers for data analysis. Examples of pressure injuries
operational definitions could be using wound assessment tools, the Braden Scale, or the NPUAP
Staging tool.
Variables are classified in several ways and all studies use several types of variables. Read in your
text about variables to complete this assignment, using the words below. Answers are only one word.
Misspelled words are counted wrong.
research independent dependent demographic extraneous environmental modifying
