Final Answer:
Graphic rating scales involve rating performance dimensions on a scale from 1 to 5, while mixed-standard scales replace graphic rating scales and categorize employees into three performance levels: good, average, and poor.
Step-by-step explanation:
Graphic Rating Scales: In this method, performance dimensions are assessed using a numerical scale ranging from 1 to 5. Each dimension is assigned a score, and the total points represent an employee's overall performance. For example, if an employee receives high scores across various dimensions, their total points would be reflective of good performance.
Mixed-Standard Scales: This approach is an alternative to graphic rating scales. Instead of using a continuous numerical scale, employees are categorized into three performance levels: good, average, and poor. This simplifies the evaluation process by providing distinct classifications. A mixed-standard scale might involve comparing an employee's performance to predefined standards, making it easier to assign an overall performance rating.
