218 QUALITATIVE DATA ANALYSIS
Figure 13.12 Adjusting for scope in presenting classification scheme
So far we have concentrated on shapes, but what about the lines which connect
these shapes? We can also use these lines to represent different types and strengths
of relationship between categories. Some of these differences may be conceptual and
some empirical. We have already discussed the logical distinction between exclusive
and inclusive relationships between categories, which we represented with the
annotation in Figure 13.14.
The relations of inclusion and exclusion are central to categorization, but as we
have seen in discussing linked data, this may not exhaust our interest in
relationships within the data. We may want to use our maps to represent other
relationships, such as causal or explanatory links. Unlike relationships of order, in
mapping such relationships we must also take into account questions about the
direction and reciprocity.
In the diagrams (Figures 13.6 to 13.9) in which we mapped out some central
relationships between categories, we failed to indicate the type of direction of the
relationships being represented. If we wanted to outline a causal connection between
categories, we failed to do so. These diagrams could only make sense if we made two
assumptions which remained implicit. One assumption was that the reader would
