Slice and Compare Surveys by Attributes

@@@ To be renamed Split and Compare Surveys By Attributes or maybe "Divide ...". A suggestion is to try this function with Badger Springs using General.Age as the dividing parameter. If multiple sites are selected, the data from each survey is analyzed separately. It would be more useful to combine all surveys and split the data once by the selected attribute set.

This function is similar to CompareSurveysByAttributes but has an additional feature. It splits the elements within a survey by the attributes of a selected attribute set. The intended usage is to compare older/younger elements within a survey. To start, a list of all exclusive choice attribute sets are displayed. Choose any set, the usual choice is General.Age.

Next, a list of all surveys is presented. Under the Nbr Choices column is the number of values each survey has for the selected attribute set. In this case, Badger Springs elements have 3 different values in General.Age. You may select one or more surveys.

Next, a list of element classes is presented together with the counts for each class. Note that any elements that do not have a selection in the selected attribute set are not included in the counts. Select a class and click the Analyze Attributes button.

Two reports appear on the next page: Common Attributes and Unique Attributes. The Common Attributes report shows how common each of the selected class attributes are when the selected surveys are sliced by the selected attribute set. Click on any attribute hyper-link to view images of the elements.

The Unique Attributes report shows the same attributes present in the Common to 1 of x portion of the Common Attributes report, but here the attributes are sliced by the selected attribute set.
