A population with mean = 7.05 and variance = 0.35 shows which distribution pattern?
The variance-to-mean relationship provides a simple index of spatial dispersion in counts from equal sampling units. A Poisson random distribution has variance approximately equal to its mean. Here the index of dispersion is 0.35/7.05 ≈ 0.05, far below 1, indicating that quadrat counts vary much less than expected under random placement. Such underdispersion corresponds to a uniform or regular spatial pattern. Regular spacing can arise through territorial behavior, interference, allelopathy, competition for resources, or deliberate spacing in managed systems. A clumped pattern would produce va
