1.为什么低层次的变量不能使用高层次变量的集中值和离散值
2.中位值 均值 实际中一定存在吗
3.均值永远是定距变量最合理的集中值吗
谢谢大家！

低层次的变量本身不具备高层次变量的所有特征，自然不能用，用了数据不就混乱了嘛。
而且也没有实际意义。

1:定义要求，如定类变量量只具有＝≠的性质，而定比变量同时具有＝≠＞＜＋－×÷的性质。可以向下兼容会损失信息，但不能向上使用。
2:可以考虑这样一个实际问题，有两个班，一个班有3名学生，一个班有2名学生，则平均每个班有多少学生？按统计学的计算方法很容易得出2.5个学生，但实际中很明显不存在这种情况，中位数同理。
3：不是，要考虑偏态(极值)的影响，这点书上记得有讲解

请问大家:5日均线在同一天上穿10日和20日均线并且当天10日均线也上穿20日均线，这样的情况很难用肉眼看清3个金叉焦点所构成的几何形态（通常为三角形），这样的情况是否也算是构成了“月价托”呢？先谢谢大家了！股票论坛 www.55188.com

别太迷信唐能通的公开课教程，所谓的托，什么五线顺上之类的都存在前提的。不要看似符合，其实，符合的不一定会单边走势。对于这点很鄙视唐能通藏着掖着，无非就是吸引眼球收费的障眼法。

唐能通是什么？我糊涂了。不过我在网上查了一下我问的这种情况好像是叫做“黄金蜘蛛”，是价托的特殊形态。

别迷信这些东西，想知道没错，别当独门绝技，股价的涨跌是多因素的，不是有了这种形态就会上涨，象这样形态不上涨的比比皆是！
