Meaning
偏差 refers to a difference or divergence from what is expected, standard, or correct. It commonly appears in scientific, technical, and statistical contexts to describe measurement errors, deviations from norms, or discrepancies between expected and actual results. The word combines 偏 (biased, inclined to one side) and 差 (difference, error).
Usage
This is a somewhat formal term frequently used in academic writing, technical reports, and professional settings. It's common in discussions of statistics, quality control, scientific experiments, and data analysis. Native speakers use it when discussing any kind of systematic or random variation from a standard or target value.
