When estimating the sample size for a proportion, the sample size required is inversely proportional to the square of the sampling error margin and directly proportional to the maximum variability of the population being studied. When π is around 0.50, the maximum variability is high, which means that the sample size required will be larger to achieve the desired level of confidence and sampling error.
