A production manager monitors the diameter and weight of bowls that are manufactured at a plant to ensure consistency. The manager collects three bowls per day and measures their diameters and weights.
Because the data has two dependent measurement variables, you can use this data to demonstrate Multivariate EWMA Chart.
|The day that the sample was collected. This column contains the subgroup sizes.
|The weight of the bowl.
|The diameter of the bowl.
