Hello, everyone, i have some question about MORISITA INDEX

does 'n' mean the number of plots per village of one sample area that I use?

if it's true, what about a sample of village of an area? it can not know the distribution pattern? because if there is only 1 district area, then if it is less than 1 it will be 0. whereas in the chi-square table there is no value for the number 0.

**additional question

if I have 6 sample villages in 3 different districts in 1 regency, how do I determine the distribution pattern of an animal? does it have to be per district? or directly from one regency?

please anyone reply my question..

thank you
