This page shows a graphical representation of the relationship between physical characteristics and perceptions. It is obtained by plotting the actual characteristics of all marketed brands on the horizontal axis and the corresponding perceptions on the vertical axis. Each marketed brand corresponds to a data point on the graph. There are 18 such graphs, one for each couple “physical characteristic × MDS dimension”; for instance Processing Power × Performance, Display Size × Performance, etc. The best-fit line and the current position of ideal points are also represented on the graph. See an example in Figure 8.
The percentage of variation explained of the regression is given in the footnote. This is another name for R². When this percentage is close to 100%, it indicates that the actual curve and the line are close to each other and that approximating the curve by the line will give meaningful results.
