How should you evaluate data limitations in fieldwork results?

• A. Rely only on a single data source.
• B. Discuss data sources, sampling, biases, errors, and extent of generalization.
• C. Increase sample size without noting biases.
• D. Ignore data limitations if results are significant.

Answer: (B)

Evaluating data limitations means looking at what you used to collect information, how you collected it, and how those choices affect what your results can actually tell you. You examine data sources (whether you relied on your own measurements, existing records, or a mix), the sampling method and how many observations you have, and where biases might creep in—like who you could reach, how questions were asked, or how an observer’s expectations might influence results. You also consider measurement errors and the reliability of instruments, plus the extent to which you can generalize findings to other places, times, or groups. Being transparent about these factors helps others judge the study’s credibility and shows how results might change with different data or methods. Relying on a single data source can skew understanding, increasing the risk of a partial view. Merely increasing sample size without addressing biases doesn’t fix underlying problems in data quality. And ignoring limitations even when results are significant is risky because significance doesn’t remove bias or guarantee broad applicability.
