Figure 2
The horizontal axis depicts four categories labeled 1, 3, 4, and 5. The vertical axis is labeled “Index value” and ranges from negative 0.1 to 0.4 in increments of 0.1 units. The plot shows two box plots for each category: A legend at the bottom states that the blue box represents “(Normalized Difference Vegetation Index) N D V I” and the red box represents “Green N D V I”. The details for the box plot are as follows: Category 1: N D V I: Lower Quartile: 0.13 Median: 0.16 Upper Quartile: 0.18 Minimum: 0.05 Maximum: 0.26 G N D V I: Lower Quartile: 0.16 Median: 0.19 Upper Quartile: 0.21 Minimum: 0.07 Maximum: 0.29 Category 3: N D V I: Lower Quartile: 0.14 Median: 0.16 Upper Quartile: 0.19 Minimum: 0.08 Maximum: 0.25 G N D V I: Lower Quartile: 0.16 Median: 0.19 Upper Quartile: 0.22 Minimum: 0.08 Maximum: 0.26 Category 4: N D V I: Lower Quartile: 0.16 Median: 0.17 Upper Quartile: 0.19 Minimum: 0.11 Maximum: 0.22 G N D V I: Lower Quartile: 0.18 Median: 0.21 Upper Quartile: 0.23 Minimum: 0.12 Maximum: 0.27 Category 5: N D V I: Lower Quartile: 0.13 Median: 0.16 Upper Quartile: 0.19 Minimum: 0.05 Maximum: 0.27 G N D V I: Lower Quartile: 0.15 Median: 0.19 Upper Quartile: 0.21 Minimum: 0.06 Maximum: 0.26 Scattered points appear above and below the whiskers in all categories, indicating outliers.
