摘要
分析了用不同方法处理具有一元线性函数关系的物理实验数据的实验标准差.结果表明,在n≥4时,用逐差法计算线性系数b的实验标准差明显小于简单平均值法,但是稍大于最小二乘法.
Experimental standard deviation of one-dimensional linear problem is analyzed. It shows that when n≥4,the experimental standard deviation of linear factor b get by successive differential method is much less than simple average method, but is a little greater than least square method.
