Question

Quizplus · Accepted Answer

Personal observation has the disadvantage of being subject to personal bias as the observer's background and personal views can influence their perception of the performance being observed. Additionally, personal observation can be time-consuming as it requires the observer to be present and attentive throughout the entire performance. Written reports, statistical reports, and oral reports are less prone to personal bias and can be quicker to review than personal observation. Standardized tests provide an objective measure of performance, but may not capture all aspects of performance and can be costly to administer.
