Explanation:

• Option a: Calculating the mean is a statistical operation that focuses on numerical values rather than data reliability and validity.
• Option b: Designing studies involves planning methods, not directly evaluating data reliability and validity.
• Option c: Critical evaluation of data's reliability (consistency) and validity (accuracy) ensures that conclusions drawn from the data are trustworthy and accurate. If data is unreliable or invalid, conclusions lack integrity.
