Hypothesis
Tool repertoire size will be larger in large populations than in small populations (2561).
Note
Marine Biodiversity, Importance of Fishing, Seasonality and Productivity, Vulnerability to Catastrophic Storms, and Drought Risk were all regressed individually along with population size to ascertain their effects on the correlation between tool repertoire size and population size. The coefficients for these "control" variables were small and none were close to significant.
| Test Name | Support | Significance | Coefficient | Tail |
|---|---|---|---|---|
| Multiple regression | Supported | Ranged from p = 0.002 to p = 0.017 | Ranged from beta = 0.724 to beta = beta = 1.04 (standardized coefficients) | UNKNOWN |
| Variable Name | Variable Type | OCM Term(s) |
