因為製品件之間的變異程度決定了群組內的全距或平均值，因此必須先分析R管制圖，所有的點將與管制界限比較，查看是否有超出界限或是異常的趨勢。點超出管制界限－如果有溢出管制界限的點存在，即很明顥地有失去管制 的情況發生，因為只有單純的共同原因存在時，一般很少會超出界限的，因此必然有特殊原因發生。所以這些點加以圈起來，以確認改善對策之施行與否。

結果 (英文) 1:

Because the degree of variation between products from the whole or part determines the mean value in the group, it must first analyze R control charts, comparison of all the points and control limits, to see if there are trends out of bounds or abnormal. Point outside the control limits - if there is an overflow control boundaries points exist, that is very clear to Hao has lost control of the situation occurs because there is only a simple common reason, will seldom out of bounds, so there must be a special reason occurred. So these points to be circled in order to confirm whether or not the implementation of improvement measures.

結果 (英文) 2:

Because the degree of variation between the pieces determines the full distance or average value within the group, the R control chart must be analyzed first, and all points will be compared to the control limits to see if there are any profilings that exceed the boundaries or are abnormal. Points beyond the regulatory boundaries - if there is a point of overflow control boundaries, i.e. there is a clear absence of control, because when only a purecommon common cause exists, it is rare to exceed the limit, and therefore there is a specific reason. So these points are circled to confirm whether the improvement measures are implemented or not.

Because the variation degree between products determines the whole distance or average value within the group, the R control chart must be analyzed first, and all points will be compared with the control limit to see whether there is a trend of exceeding the limit or abnormal. Point out of control limit - if there is a point of overflow control limit, that is to say, there is clearly a situation of deregulation. Because there is only a simple common reason, it is rarely beyond the limit, so there must be special reasons. So these points should be circled to confirm whether the improvement measures are implemented or not.
