Measures of population distribution Index of dissimilarity, D Measure of spread of two groups possible values 0-1 0 = the groups are equally spread (e.g., all zones have a 65/35 split of two groups) 1 = the groups are completely uneven (all zones are 100% one group and 0% of the other) Moran's I (autocorrelation coefficient) A measure of the correlation between data values and neighbouring data values (thus, a measure of clustering) Unlike correlation coefficient, not strictly constrained to -1, 1 Positive values = clustering; negative values = neighbouring values tend to be different
