* don’t exist -- “the product of informed

Linda Crocker and James Algina described constructs as “the product of informed scientific imagination.” Constructs represent something that is abstract, but can be operationalized through the measurement process. Measurement can involve a paper and pencil test, a performance, or some other activity through observation which would then produce variables that can be quantified, manipulated, and analyzed.
