Figure A1
The horizontal axis is labeled “Number of Clusters (K)” and ranges from 2 to 10 in increments of 2 units. The vertical axis is labeled “Cluster Inertia – Total-Within-Clusters-Sum-of-Squares (T W S S)” and ranges from 17,500 to 35,000 in increments of 2,500 units. The graph shows a single line with circular markers representing the total within-cluster sum of squares for each cluster number. The line begins at (1, 34,240.51), (2, 30,316.46), (3, 27,278.48), (4, 25,284.81), (5, 23,575.95), (6, 22,658.23), (7, 21,265.82), (8, 20411.39), (9, 19936.71), (10, 19,018.99), (11, 18196.2). Note: All numerical data values are approximated.Elbow plot of KMeans cluster analysis. Source: Representation based on own calculation
