Statistical Applets: Sampling Distribution of a Proportion

If the sample size, n, is "large" and both np and n(1 - p) are large enough, the sampling distribution of the sample proportion  = X/n will be approximately a Normal distribution with mean μ = p and standard deviation:

σ=p(1−p)n

This applet illustrates that important fact by allowing you to generate individual samples or thousands of samples with the specified parameters. You can then compare the distribution of sample proportion against the Normal distribution predicted from the parameters.
