for calculations from Table 5.42. bThe diversity of tool types was calculated using a formula from Zar (1974): fi=frequency of categories I (number of tools for each type in this case) k=number of categories (8 tool types) n=sample size (total number of tools recorded for a site group) This formula measures evenness. If all the tool categories had the same quantity of tools in them the J score would be 1.0. See Reid (1982) and Kintigh (1984) for a more complete description. |
