Document Summary
In the literature - reporting the results of a binomial test. 18. 3 the relationship between chi-square and the binomial test. Learning objectives and chapter summary: students should recognize binomial data and be able to identify situations where a binomial test is appropriate. Binomial data exist whenever individuals are classified into exactly two different categories. A binomial test is appropriate when there is a question about the proportion of individuals in each category: students should understand the normal approximation to the binomial distribution and when it is appropriate to use the approximation. When pn and qn are both greater than or equal to 10, the binomial distribution is approximately normal with a mean of = pn and a standard deviation of = npq. In this situation, individual scores can be converted to z-scores and probabilities can be obtained from the unit normal table.
