问个很菜鸟的问题

假设一个零件的跳动要求0.02MAX,测得的数据如下,0.005 ,0.009 ,0.006 ,0.007,0.009 ,0.010 ,0.006 ,0.006 ,0.008 ,0.007 ,0.008 ,0.006 ,0.008 ,0.009 ,0.005 ,0.009 ,0.011 ,0.004 ,0.008 ,0.005 ,0.008 ,0.010 ,0.005 ,0.011 ,0.006 ,0.006 ,0.007 ,0.010 ,0.006 ,0.006 ,0.009 ,0.010 ,首先它不符合正态分布,用非正态的能力分析方法,它的PPM为0,请问,不符合正态分布的数据,分析出的PPM永远等于0吗??
