Answer:
by demonstrating that raises of different sizes are associated with differences in performance.
Step-by-step explanation:
In this scenario Yolanda receives a 2 percent increase in salary. Later that day, while talking to Marvin, she learns that his pay increase was 4 percent.
The best way that human resources can explain this to Yolanda is that based on performance there was an increase in salary. Yolanda's performance resulted in a 2% increase while that of Marvin resulted in a 4% increase.
Apart from expressing the fairness of the salary increase it will motivate Yolanda to perform better so she will be able to get a higher raise in the future.
