Step-by-step explanation:
In a Functional Job Analysis, tasks are rated on three factors: people, things, and Data. The correct answer to the question is D) data. Job analysis is a critical tool in industrial and organizational psychology for understanding the demands of a job, and it includes observation, surveys, interviews, and potentially other forms of data gathering to provide a comprehensive picture of a job's requirements.
Researchers such as Dierdorff & Wilson have indicated that the reliability of job analysis can vary depending on who provides the information, with job incumbents sometimes being less reliable sources than others. Moreover, job satisfaction can be influenced by various factors, and employee surveys, such as the Federal Employee Viewpoint Survey, can reveal insights into these aspects.
