formalized
C) The appropriate application of wisdom
D) Data entered into a spreadsheet
pg. 3
, 4
Answer: B)
Rationale: Knowledge involves synthesizing multiple sources of information to
create conceptual frameworks, theories, and axioms.
10. Wisdom is defined as:
A) A collection of data points
B) Interpreted data organized into a structure
C) Appropriate use of knowledge to manage and solve human problems
D) The systematic study of information
Answer: C)
Rationale: Wisdom represents the highest level of the DIKW continuum—the
