Y, Columns

Assigns the variables that you want to analyze. A histogram and associated reports appear for each variable.

Weight

Assigns a variable that specifies weights for observations on continuous Ys. For categorical Ys, the Weight column is ignored. Any statistic that is based on the sum of the weights is affected by weights.

Freq

Assigns a frequency variable to this role. This is useful if your data are summarized. In this instance, you have one column for the Y values and another column for the frequency of occurrence of the Y values. The sum of this variable is included in the overall count appearing in the Summary Statistics report (represented by N). All other moment statistics (mean, standard deviation, and so on) are also affected by the Freq variable.

By

Produces a separate report for each level of the By variable. If more than one By variable is assigned, a separate report is produced for each possible combination of the levels of the By variables.

Create Process Capability

(Appears only if a column contains a Spec Limits column property.) Adds a Process Capability report for the analysis columns that contain a Spec Limits column property.

Histograms Only

Removes everything except the histograms from the report window.
