Which description best defines a 'trade-off' in research methods?

• A. A choice between increased sample size and improved precision
• B. A choice between two desirable but conflicting goals
• C. An unchangeable property of a system
• D. A guarantee of results

Answer: (B)

In research methods, a trade-off happens when you must balance two desirable but conflicting goals because resources, time, or practicality prevent you from optimizing both at once. The best description is therefore a balance between two desirable but conflicting goals, since that phrase captures the idea of choosing one objective while giving up some degree of the other. The other options miss this core idea: an unchangeable property isn’t about balancing competing aims, and a guarantee of results isn’t about trade-offs at all. While choosing between sample size and precision can illustrate a trade-off in practice, the general definition is accurately described by acknowledging two desirable but conflicting goals.
