Which statement best describes an advantage of field testing over lab testing?

• A. Smaller participant pool
• B. More expensive equipment
• C. Higher control of conditions
• D. Cost and time efficiency with large pool

Answer: (D)

Field testing is advantageous when you want to evaluate performance with many people in a real-world setting, which often means lower costs and quicker data collection. Because you aren’t building a controlled lab environment, you can recruit a larger number of participants and run tests in natural contexts, saving time and money. This is in contrast to lab testing, where the emphasis is on precise control and typically requires more equipment, setup, and resources, limiting the number of participants and increasing cost and duration. The best choice captures this practical benefit: being able to test a large pool efficiently in terms of both cost and time.
