Figure 5. Comparative distributions of sediment abundances showing the effect of spatial clustering on summary statistics. (A) sediment abundance data derived from spatially clustered boreholes may bias the statistics that summarize the central tendency and (or) spread of a distribution; (B) effect of redundant information is reduced by assigning appropriate declustering weights, leading to more representative summary statistics. Sample standard deviation is denoted by s.
