Figure 2
The vertical axis is labeled “Eigenvalue” and ranges from 0 to 14 in increments of 2 units. The horizontal axis is labeled “Factor number” and ranges from 1 to 51 in increments of 2 units. There is one series represented by a solid line with circular markers. The series starts at factor number 1 with an eigenvalue of 14.5, drops sharply to 6.2 at factor number 2, then decreases to 4.6 at factor number 3 and to 2.0 at factor number 4. From factor number 5 onward, the values decline gradually from 1.4 to below 1 and then continue to decrease slowly, approaching 0.3 to end at factor number 51. Note: All numerical data values are approximated.Scree plot. Source: Authors’ own work
