As a f<strong>in</strong>al element, the realtor has John and Mary add the conceptual element, "Ideal home", and rate it on the exist<strong>in</strong>g<br />

constructs. This def<strong>in</strong>es the preferred value, usually a "preferred pole", on each construct for WebGrid. The users now<br />

chose one of the analysis programs, Pr<strong>in</strong>Com, to generate a map of the relations between constructs and elements.<br />

Pr<strong>in</strong>Com does a pr<strong>in</strong>cipal components analysis of the grid data, attempt<strong>in</strong>g to represent it <strong>in</strong> as few dimensions as<br />

possible. WebGrid plots the first two components and returns them as a GIF as shown <strong>in</strong> Figure 10. It can be seen that<br />

there are two major clusters of dimensions characterized by "Friendly--Oppressive" and "Extensive<br />

modernization--Orig<strong>in</strong>al condition". It can also be seen that "Ideal home" clusters most strongly with "1, Abraham<br />

Po<strong>in</strong>t".<br />

The users also use the FOCUS analysis program to sort the grid so that similar elements and similar constructs are<br />

clustered together. WebGrid graphs the data and returns it as a GIF as shown <strong>in</strong> Figure 11. Aga<strong>in</strong>, it can be seen that "1,<br />

Abraham Po<strong>in</strong>t, NW" is closest to be<strong>in</strong>g the "Ideal home". Because the orig<strong>in</strong>al grid data is shown, it is possible to see<br />

how this home and the others differ from the ideal.
