Several of the techniques in the statistical tools section have the option of using stacked or unstacked data. This simply refers to how the data are entered into the worksheet. The two methods are described below.
Stacked Data Entry
The stacked data entry is shown below. The treatment levels are in one column and the responses are in another column.
Unstacked Data Entry
The unstacked data entry is shown below. There are five different processes or treatments. These are labeled A – E with the labels in the same row. The observations for each treatment are listed in the column under the treatment heading. For example, for treatment A, the observations are 250, 260, 230, and 270.
