误差传播规律是计算抽样调查精度的重要手段,各种抽样方法误差计算公式虽有所不同,但都是按照误差传播规律推导演变而成的,为便于学习和分析有关误差计算,现将两
The law of error propagation is an important means of calculating the precision of sampling. Although the formulas for calculating the error of sampling methods vary, they are derived from the law of error propagation. To facilitate learning and analysis of the error calculation,
