Operationalization is ________.
a) a statement that attempts to predict a set of phenomena and specifies relationships among variables that can be empirically tested
b) an organized system of assumptions and principles that purports to explain a specified set of phenomena and their interrelationships
Incorrect. Operationalization is not based on assumptions.
c) the precise meaning of a term used to describe a variable, such as a type of behavior, which researchers want to measure
Correct. Preciseness is essential for the scientific method.
d) the principle that a scientific theory must make predictions that are specific enough to expose the theory to the possibility of disconfirmation
