Web$\begingroup$ @DanWu, you’re right that the binomial test is more cumbersome to work with for large n, but this only true if you’re calculating the results by hand.As long as you use R, there is no problem. And for large n it doesn’t matter, as both functions give approximately the same answer. But do note that prop.test() uses the score test, not a … WebThis procedure calculates sample size and statistical power for testing a single proportion using either the exact test or other approximate z-tests.
