I used the direct anchor method.

The anchor question consists of a subset of items, based on a constructed list.

The constructed list is based on the following logic:

ADD (MXDList, MaxDiffRankAttValue(MXD, 1))

ADD (MXDList, MaxDiffRankAttValue(MXD, 5))

ADD (MXDList, MaxDiffRankAttValue(MXD, 10))

ADD (MXDList, MaxDiffRankAttValue(MXD, 15))

ADD (MXDList, MaxDiffRankAttValue(MXD, 20))

ADD (MXDList, MaxDiffRankAttValue(MXD, 25))

The anchor question was: 'Which of these are important to you?'

How do I analyze this data; including the anchor treshold?

In other words: what logic do I use in the analysis tool?

Thanks!
