Question
A Green Belt wishes to sample castings due to some parts being out of tolerance. Which of the following multi-vari sampling techniques would be used for batch to batch sampling?
A temporal study is to assess variance over time
The temporal variation category is also known as time-to-time variation.when we consider that magnitude of variation between the segments of the process separated by a significant amount of time, that is considered as temporal variation.
Also If this type of variation is large, the factor driving process performance must be one that belongs to the temporal category; otherwise, the factor must be from another category.
