It ensures your data is enough to detect true effects or differences, avoiding wasteful excess or insufficient information. Factors like the desired confidence level, expected variability, and the precision of results influence this number. In simple terms, it helps you balance collecting enough data to be confident in your conclusions without gathering unnecessary information, making your research efficient and trustworthy.
