Final answer:
Administering psychological inventories requires knowledge of testing principles and measurement error as well as sensitivity to one's own limitations.
Step-by-step explanation:
When administering psychological inventories, it is important to have knowledge of testing principles and measurement error (a) and sensitivity to one's own limitations (b). These two factors ensure that the assessments are accurate and reliable. Using psychological tests for optimal team selection (c) is not necessarily important when administering psychological inventories as it is more relevant to a different context, such as human resources or sports management.
