- Table 17c gives estimates of assemblage diversity and richness for the Puritjarra occupations. Following Odum (1971: 144), richness is number of tool types/log (sample size), and diversity is the Shannon-Weaver diversity index (H') (Odum, 1971: 144). Richness is standardized against log(sample size) to remove the effect of sample size on number of tool types. The results in Table 17c show that site inventories (richness) increase over time, with unit 1a being noticeably richer than other units. Similarly, diversity increases over time, and unit 1a has the most diverse assemblage. Both indices identify unit 1c as an anomaly in this trend, with a more limited site inventory.
- Barton (2003: table 5) includes comparative data for open sites in the Simpson Desert. Values for unit 1a are comparable to those for residential base camps, near springs in the Simpson Desert (richness 5.44; diversity 1.58). Site inventories in units 2b-d are conspicuously poorer than anything in Barton's sample. Veth (2005a: table 6.6) provides figures for artefact diversity on Western Desert sites (8.0 for base camps; 4.0 for ephemeral residential camps; 2.0 for task specific sites). These figures are higher than in any unit at Puritjarra, but may not be strictly comparable: That they are so much higher than those in the
