Table 2 Indices of knowledge and uses calculated for P. biglobosa.
From: Ethnic differences in use values and use patterns of Parkia biglobosa in Northern Benin
Index | Calculation | Description | Reference |
|---|---|---|---|
Interviewee diversity value (ID) ID = Ux/Ut | ID, number of uses-citations by a given interviewee (Ux) divided by the total number of uses (Ut) | Measures how many interviewees used Parkia biglobosa and how its uses are distributed among the interviewees | [17] |
Interviewee equitability value (IE) IE = ID/IDmax | IE, interviewee diversity value (ID) divided by this index's maximum value (IDmax) | Measures the degree of homogeneity of the interviewee's knowledge | [17] |
Consensus value for plant parts (CPP) CPP = Px/Pt | CPP, number of times a given plant part was cited (Px) divided by the total number of citations of all parts (Pt) | Measures the degree of agreement among interviewees concerning the plant part used | [18] |
Use diversity value (UD) UD = Ucx/Uct | UD, number of indications recorded by category (Ucx) divided by the total number of indications for all categories (Uct) | Measures the importance of the use categories and how they contribute to the total value of uses | [17] |
Use equitability value (UE) UE = UD/UDmax | UE, use-diversity value (UD) divided by the index's maximum value (UDmax) | Measures the degree of homogeneity of knowledge about use categories | [17] |
Consensus value for the form of use (CMU) CMU = Mx/Mt | CMU, number of citations for a given form of use (Mx) divided by the total number of citations for all forms (Mt) | Measures the degree of agreement among interviewees concerning the form of use of Parkia biglobosa | [18] |
