A common method of measuring performance in many college and university courses is to combine objective measures (test scores, for example) with subjective measures (class participation measures, for example). These scores are weighted and combined to determine a final grade. 

Required

a. Write a memo that discusses the advantages and disadvantages of using multiple measures of performance, including some that are objective and some that are subjective.

b. Can you identify a situation in which you would prefer to be evaluated using a purely objective measure (exam scores)? A purely subjective measure (class participation)?
