Sampling from a fairly homogenous population would increase the precision of a population estimate because it would reduce the variability within the sample and provide a more representative sample of the population. Smaller sample sizes, a larger standard error of the sample mean, and increasing the sampling frame could all potentially decrease the precision of the estimate.
