Thus a per cent R of 50 indicates the B. alluaudi Hes exactly halfway between the other two. The probability, P, refers to the probabihty of observing a mean equal to the B. alluaudi value had the sample come from one of the other two species. Thus, for H, the probability of observing a mean of 23-10 is o-i for V. rtcwenzorii and o-i for B. somereni.
