WebOct 21, 2024 · Then the binomial can be approximated by the normal distribution with mean μ = n p and standard deviation σ = n p q. Remember that q = 1 − p. In order to get the best approximation, add 0.5 to x or subtract 0.5 from x (use x + 0.5 or x − 0.5 ). The number 0.5 is called the continuity correction factor and is used in the following example. WebThe random variable X counts the number of successes obtained in the n independent trials. X ~ B ( n, p) Read this as “ X is a random variable with a binomial distribution.”. The parameters are n and p: n = number of trials, p = probability of a success on each trial. Since the Binomial counts the number of successes, x, in n trials, the ...
