Final answer:
The judgmental strategy involves gathering evidence and making a judgment based on that evidence, while the mechanical strategy involves assigning numerical values to factors and calculating an overall score.
Step-by-step explanation:
The two strategies for obtaining an overall performance score are the judgmental strategy and the mechanical strategy.
The judgmental strategy involves gathering evidence and making a judgment based on that evidence. For example, when evaluating a film, you might watch it multiple times and focus on specific elements of the evaluation criteria. Similarly, when evaluating an employee, you might observe them in different situations to gather evidence.
The mechanical strategy involves assigning numerical values to different factors and calculating an overall score. For instance, when deciding on the best option among several choices, you might assign a number on a scale from 1 to 10 for each factor and calculate the total score. This strategy helps to clarify the option that is best based on the assigned values.
