摘要

　研究了异常点对相关系数的影响.结果表明:异常点对相关系数的影响主要反映在异常点对数据离散程度的影响、对均值点的影响以及异常点偏离均值点的程度.

Abstract

The influence of singular point on correlation coefficient is researched. The result indicates that this influence is chiefly reflected in the singular point′s impact on mean point and the degree of singular point′s deviation from mean point.
