Which usability study is described for evaluating data-entry methods in the material?

• A. Usability study comparing clinic kiosks to in-person interviews
• B. Double-blind drug trial
• C. Telemedicine video quality assessment
• D. Blood pressure measurement protocol

Answer: (A)

Evaluating how people enter data requires a usability approach that directly tests the interaction with different data-entry tools. Describing a study that compares a patient-facing clinic kiosk to traditional in-person interviews fits this goal, because it examines how easily and efficiently users can input information, where they encounter errors, and how satisfied they are with each method. This kind of comparison provides practical insights into which data-entry method yields better usability for collecting information. The other options probe different areas: a double-blind drug trial looks at efficacy and bias rather than data-entry methods; a telemedicine video quality assessment focuses on the technical quality of audiovisual transmission; and a blood pressure measurement protocol is about standardizing a clinical procedure, not about how data is entered.
