If a field data collection method yields similar results when the study is repeated in the same area, the method is described as:

• A. Valid
• B. Reliable
• C. Biased
• D. Inaccurate

Answer: (B)

Reliability is about consistency of results. If you repeat field data collection in the same area and obtain similar results each time, the method is reliable because it produces measurements that are repeatable under the same conditions. This repeatability means you can trust the method to give stable data across similar trials. It doesn’t automatically guarantee accuracy or validity, since you could be consistently off in what you measure or biased in how you collect data. For instance, you might consistently miss a feature, yielding the same wrong result each time, which would be reliable but not valid. So the description fits reliability because of the demonstrated repeatability of findings.
