Figure 6.12 Example of a 3-D Scatterplot
From Figure 6.12, notice the following:
• Looking at the c1 axis, responses 1 through 5 appear to the right of 0 (positive). Responses 6 through 9
appear to the left of 0 (negative).
• Looking at the c2 axis, A and C appear to the right of 0 (positive). B and D appear to the left of 0
(negative).
• You can have two conclusions: c1 corresponds to the general satisfaction (from least to most liked). c2
corresponds to a quality that makes B and D different from A and C.
