Figure 3
The line graph shows eigenvalues on the vertical axis and factor numbers on the horizontal axis. The vertical axis ranges from 0 to 12, while the horizontal axis ranges from 1 to 27. The graph features a single data line with blue markers at each data point. The eigenvalues start at approximately 11 for factor number 1 and drop sharply to around 2 for factor number 2. From factor number 3 onwards, the eigenvalues gradually decrease and level off, remaining close to 1 for the remaining factor numbers. This pattern indicates a significant drop in eigenvalues after the first few factors, suggesting the presence of a few dominant factors.Scree plot
