Dear Reader,(adsbygoogle = window.adsbygoogle || []).push({});

I am writing for information, or a point towards any information about the calculation on the uncertainty on the number of trials in a binomial distribution. I had been using the SQRT(N) (taken from poisson dist. I miss them) but forgot they are binomial. For example if I toss a coin 100 times, (lands 50 heads 50 tails), what would the uncertainty/error be on that 100 trials? That is to say 100 +/- ?. Thank you for your help,

Kim
