  • Constructs
Constructs: A construct is anything that is difficult to measure because it can be defined and measured in many different ways.

Example: Volume is a construct. We know volume is the space something
takes up but we haven’t defined how we are measuring that space. (i.e.
liters, gallons, etc.)

Operational Definition: The operational definition
of a construct is the unit of measurement we are using for the
construct. Once we operationally define something it is no longer a
construct.
Example: Minutes is already operationally defined; there is no ambiguity in what we are measuring.
