We know from our Data Preparation phase that we have some data that need to be fixed
before we can mine this data set. Specifically, Gill noticed some inconsistencies in the
Decision_Making attribute. Run your model and let's examine the meta data, as seen in
Figure 7-2.

While still in results perspective, switch to the Data View radio button. Click on the
column heading for the Decision_Making attribute. This will sort the attribute from
smallest to largest (note the small triangle indicating that the data are sorted in ascending
order using this attribute). In this view (Figure 7-3) we see that we have three observations
with scores smaller than three. We will need to handle these observations.
