Survey Questionnaire

A construct is typically made up of phenomena that are not measurable in the physical world. Constructs represent ideas and concepts (i.e. attitudes, beliefs, etc.) about how the the world works. Since many phenomena cannot be physically sensed (i.e. seen, heard, or touched), we must develop tools for measuring human perceptions of these ideas and concepts.

A person's interest to edit Wikipedia is a good example of a construct. Interest cannot be measured with a ruler or weight scale. It is a combination of qualities in a person that need to be assessed through some other measurement tool, like asking a question about interest in a survey.
