【摘要】 在对实验数据进行线性回归分析时,相关系数r的计算结果会随数据小数位数的取舍而变化,表现出较大的涨落性.通过对比分析提出,应尽量保留中间量的小数位数,避免不当的简化计算,以保证结果的准确性更多还原

【Abstract】 When regressive analysis is made on groups of experimental data, the results of correlation coefficient change with the acceptance or rejection of places of decimals, and display fluctuation to a certain degree. So it is induced through analysis and contrast that the places of decimals be retain as many as possible for the accuracy of the results.更多还原
