When can a chi-squared test be used for binomial data?

SUMMARY. Health services research data often consist of clusters of binary observations, such as serial observations of patients over the course of a hospi. Aug 29, 2014 ... I'm trying to plot the pmf of the binomial distribution for particular values of N and p. For example, when N=10 and p=0.5. Normal distribution describes continuous data which have a symmetric distribution, with a characteristic 'bell' shape. The binomial distribution represents the probability for 'x' successes of an experiment in 'n' trials, given a success probability 'p' for each trial at the ... The Binomial Distribution · There are a fixed number of experiments/trials, n n . · There are only two possible outcomes for each trial, usually called 'success ... Note that the four outcomes are equally likely: each has probability 1/4. To see this, note that the tosses of the coin are independent (neither affects the ... Key Highlights · Binomial distribution is a probability distribution that represents the number of trials where each trial has the same chance of achieving a ... Constructor Summary. BinomialDistribution() Default constructor: creates the binomial distribution with 10 trials and probability of success 1/2. Binomial probability refers to the probability of exactly x successes on n repeated trials in an experiment which has two possible outcomes. In probability theory and statistics, the binomial distribution is the discrete probability distribution that gives only two possible results in an ...
