Part I
A construct is a concept, idea, or condition requiring study. The following table provides information on either a construct, scale of measurement, or justification of how the scale of measurement measures a construct. Complete the blank cells. In those rows that are missing a specific construct, look up the method of measurement and identify what construct you believe is being measured. Within the empty cells in column two, find a popular way that each construct is measured, such as a scale, questionnaire, survey, and so on. In column three, provide a justification for what is being measured. In the last row of this table, choose one construct on your own and fill in the remaining columns. All of the constructs and scales of measurement chosen can be identified using any search engine.
