Figure 3
The scatter plot shows absorbance values against G N P s in gram for lab measurements and E P R pre measurements. G N P s range from about 0.12 gram to about 0.9 gram, and absorbance ranges from about 0.1 to about 0.85. At about 0.12 gram, values are about 0.20 for lab and about 0.11 for E P R pre. At about 0.17 gram, values are about 0.27 for lab and about 0.22 for E P R pre. At about 0.22 gram, values are about 0.34 for lab and about 0.30 for E P R pre. At about 0.35 gram, values are about 0.48 for lab and about 0.48 for E P R pre. At about 0.45 gram, values are about 0.64 for lab and about 0.57 for E P R pre. At about 0.9 gram, values are about 0.84 for lab and about 0.83 for E P R pre. The graph also shows R squared value 0.939 and R M S E value 0.054.EPR prediction and laboratory test analysis for holding time
