processing applications
C) Both A and B
D) None of the above
Answer: C) Both A and B

better
B) To determine if there are any significant differences between two
data sets
C) Both A and B
D) None of the above
Answer: C) Both A and B

4. In a business context, which of the following best defines 'data
mining'?
A) The process of finding anomalies, patterns, and correlations within
large data sets to predict outcomes
B) A technique used to extract usable data from a larger set of any raw

D) None of the above
Answer: C) Both A and B
Rationale: Data mining involves processing large data sets to identify

making process?
A) Data collection
B) Data analysis
C) Data interpretation
D) All of the above
Answer: D) All of the above
Rationale: A data-driven decision-making process involves collecting

Which of the following best describes the concept of data-driven
decision-making?
A) Making decisions based on intuition and gut feeling
B) Making decisions solely based on historical data
C) Making decisions based on analysis and interpretation of data
D) Making decisions without considering any data
Answer: C) Making decisions based on analysis and interpretation of
