From: A review of forest and tree plantation biomass equations in Indonesia
The boxplot displays the variation in “r 2” values for the biomass equations in Indonesia. The boxes indicate the interquartile range and encompass 50 % of the data values. The error bars represent the 10 to 90 % range of the values, and the open circles and asterisks indicate data points that are located at least 1.5 and 3 times away from the interquartile range, respectively
