In compensation and benefits management, what primary objective does a scattergram (scatter plot) serve when establishing wage structures and pay levels?

In wage and salary administration, a scattergram is a graphical tool used to depict the relationship between job worth and pay rates: X-axis (Horizontal): Represents internal job worth, usually quantified as job evaluation points or point scores obtained through methods like the Point-Factor System. Y-axis (Vertical): Represents external market wage rates (salary survey data) or current organizational pay rates. By plotting these points, organizations create a visual representation that allows compensation specialists to draw a wage trend line (pay policy line). This helps establish fair pay grades, detect pay inequities (e.g., green-circle or red-circle rates), and ensure internal equity is aligned with external competitiveness.
