Abstract The measurement of departure from randomness in spatial distributions has widespread application in ecological work. Several "indices of non-randomness" are compared with regard to their dependence on sample number, sample size and density. Criteria for the best choice of index for specific situations are discussed. A new coefficient C x is proposed for use with positively contagious distributions and tests of significance are given. When C x and another index (S 2/m-1) are used for positive and negative contagion respectively, values ranging from -1 through 0 (random) to +1 are obtained, regardless of sample number, sample size or density.
