A Simple Technique to Estimate the Flammability Index of Moroccan Forest Fuels

Table 3

Analysis of variance of the four sampling sizes applied to determine the flammability index (FI) through laboratory experimental tests performed on 31 tree and shrub species.

Source of variation	Sum of squares	Degree of freedom	Mean square	𝐹-test	Probability	𝐹-value
FI-calculating methods	0.6672	3	0.2224	0.1251 n.s.	0.9453	2.622
Residual error	938.8316	528	1.7781
Totals	939.4988	531

n.s.: no significant effect at 𝛼=0.05.
