Binomial Proportion Sample Size Calculator. To learn more about the binomial distribution go to Stat Treks tutorial on the binomial distribution. SE p sqrt p 1 - p n where p is Proportion of successes in the samplen is Number of observations in the sample.
The binomial probability is a type of discrete probability distribution that can take random values on the range of 0 n where n is the sample size. The sample proportion is what you expect the results to be. Inference for a single Proportion.
XSimply enter the probability of observing an event outcome of interest success on a single trial eg.
The calculations are the customary ones based on the normal approximation to the binomial distribution.
