Continuity correction
In mathematics, a continuity correction is an adjustment made when a discrete object is approximated using a continuous object. == Examples == === Binomial === If a random variable X has a binomial distribution with parameters n and p, i.e., X is distributed as the number of "successes" in n independent Bernoulli trials with probability p of success on each trial, then P ( X ≤ x ) = P ( X < x + 1 ) {\displaystyle P(X\leq x)=P(X<x+1)} for any x ∈ {0, 1, 2, ...
