Meaning
误差 refers to the difference between a measured, calculated, or observed value and the true, correct, or expected value. It is commonly used in scientific, technical, and mathematical contexts to describe inaccuracies or variations in measurements, experiments, or calculations.
Usage
This is a formal, technical term used primarily in academic, scientific, engineering, and statistical contexts. Native speakers use it when discussing precision in measurements, experimental results, or calculations. It often appears with words like 减少 (reduce), 控制 (control), or 允许 (permissible).
Examples
- 01这次实验的误差范围在百分之三以内。.The margin of error for this experiment is within three percent.
- 02为了减少测量误差，我们需要使用更精密的仪器。, .In order to reduce measurement error, we need to use more precise instruments.

Origin
The word combines 误 (mistake/error) with 差 (difference), literally meaning 'error difference' or 'mistaken discrepancy,' which evolved to mean the deviation from a correct value.
