THE SCIENTIFIC METHOD AND DESCRIPTION

Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
An operationalised variable is one that is
A
uncontrollable
B
predictable
C
measurable
D
correlational
Explanation: 

Detailed explanation-1: -Operationalization is the process of strictly defining variables into measurable factors. The process defines fuzzy concepts and allows them to be measured, empirically and quantitatively.

Detailed explanation-2: -Operational definition is a statement of the specific dimensions and elements through which a concept will become measurable. Operationalizing is done by looking at the behavioral dimensions, or properties denoted by the concept. These are then translated into observable and measurable elements.

Detailed explanation-3: -Numeric variables have values that describe a measurable quantity as a number, like ‘how many’ or ‘how much’. Therefore numeric variables are quantitative variables.

Detailed explanation-4: -Operationalization can be defined as the process of turning abstract concepts into measurable observations. It involves defining how a concept can be measured, observed, or manipulated. Using operationalization, researchers can systematically collect and evaluate phenomena that can’t be observed directly.
