股票变异系数越大说明什么？

股票变异系数越大说明以均数为准变异程度大。变异系数是反应离散趋势的，变异系数越大，反应以均数为准的变异程度大。变异（偏离）程度越大，风险也就越大。 变异系数又称“标准差率”，是衡量资料中各观测值...

股票变异系数越大说明以均数为准变异程度大。变异系数是反应离散趋势的，变异系数越大，反应以均数为准的变异程度大。变异（偏离）程度越大，风险也就越大。

变异系数又称“标准差率”，是衡量资料中各观测值变异程度的另一个统计量。当进行两个或多个资料变异程度的比较时，如果度量单位与平均数相同，可以直接利用标准差来比较。如果单位和（或）平均数不同时，比较其变异程度就不能采用标准差，而需采用标准差与平均数的比值（相对值）来比较。

MCSE boot camps have its supporters and its detractors. Some people do not understand why you should have to spend money on boot camp when you can get the MCSE study materials yourself at a fraction of the camp price. However, who has the willpower to actually sit through a self-imposed MCSE training.
