Variable General Info
Metric range ?Comment:The range is the distribution of metric values across all of the available data. The goal is to eliminate metrics that have very small ranges (e.g., richness metrics based on only a few taxa) or that have similar values at most sites (e.g., most sites have values ¼ 0). A small range could indicate that a metric might not vary sufficiently across sites to discriminate among sites in different conditions. |
