Average Menu (in Distance Data Explorer)

This menu is used for the computation of average values using the selected taxa A taxon is the individual unit whose evolutionary relationship is being investigated. Depending on the study, “taxa” may refer to species, populations, individuals, or sequences within an individual..  The following averaging options are available:

Overall:  This computes and displays the overall average.

Within groups:  This is enabled only if at least one group is defined.  For each group, an arithmetic average is computed for all valid pairwise comparisons and results are displayed in the Distance Matrix Explorer.  All incalculable within-group averages are shown with a red “n/c”.

Between groups:  This is enabled only if at least two groups of taxa A taxon is the individual unit whose evolutionary relationship is being investigated. Depending on the study, “taxa” may refer to species, populations, individuals, or sequences within an individual. are defined.  For each between group averages, an arithmetic average is computed for all valid inter-group pairwise comparisons and results are displayed in the Distance Matrix Explorer.  All incalculable within group averages are shown with a red “n/c”.

Net Between Groups:  This computes net average distances between groups of taxa A taxon is the individual unit whose evolutionary relationship is being investigated. Depending on the study, “taxa” may refer to species, populations, individuals, or sequences within an individual.RH_Groups_of_taxa and is enabled only if at least two groups of taxa A taxon is the individual unit whose evolutionary relationship is being investigated. Depending on the study, “taxa” may refer to species, populations, individuals, or sequences within an individual. with at least two taxa A taxon is the individual unit whose evolutionary relationship is being investigated. Depending on the study, “taxa” may refer to species, populations, individuals, or sequences within an individual. each are defined.RH_Groups_of_taxa  The net average distance between two groups is given by

d_A = d_XY – (d_X + d_Y)/2

where, d_XY is the average distance between groups X and Y, and d_X and d_Y are the mean within-group distances.   All incalculable within group averages are shown with a red “n/c”.
