Figure . Total capacitance (F) as reported by participating groups for (a) File 1, from an ideal supercapacitor, and (b) File 2, from a non-ideal device. Plots on the left show all data points reported and plots on the right show a zoomed-in view of the enclosed section, highlighting the data distribution about the adjusted mean average. This is the mean average obtained after omitting anomalous values that were calculated using incorrect methods. For File 1, these values are excluded from the enclosed section of the plot. σ is the standard deviation in the adjusted mean values. The adjusted mean value for File 1 is 0.172 F. No adjusted mean average value was calculated for File 2 as the use of different equations during the analysis of this file makes the criteria for classification of an anomaly unclear. The highlighted data point in the results of File 2 (blue) is the total capacitance reported by Group 3.
