Unveiling the drives behind tetracycline adsorption capacity with biochar through machine learning

Statistical results of biochar characteristics

This study utilized a combination of box plots and normal distribution curves to illustrate the distribution patterns of continuous data (see Fig. 1). The composite plot comprises two sections—the left segment illustrates the box plot, whereas the right segment manifests the normal distribution curve of the data. The box plot depicts the median, signified by a white dot, the interquartile range, denoted by the box, and the whiskers, which represent the remaining data. Outliers are designated by circular points or alternative symbols. The…
