Are you still using 0.5 as a threshold? Your Data Teacher

WebbSuppose you have a large number of trials and want to estimate the success probability p. If X is the observed number of successes in n trials, then the estimate is p ^ = X / n. Also, if n is large enough a reasonably good 95% confidence interval for p ^ is p ^ ± 1.96 p ^ ( 1 − p ^) / n. This provides an indication how close p ^ is to the ...
