The sign test is a special case of the binomial test where the probability of success under the null hypothesis is p=0.5. Thus, the sign test can be performed using the binomial test, which is provided in most statistical software programs. On-line calculators for the sign test can be founded by searching for "sign test calculator".
The binomial test is useful to test hypotheses about the probability of success: : = where is a user-defined value between 0 and 1.. If in a sample of size there are successes, while we expect , the formula of the binomial distribution gives the probability of finding this value:
The binomial sign test gives an exact test for the McNemar's test. The Cochran's Q test is an extension of the McNemar's test for more than two "treatments". The Liddell's exact test is an exact alternative to McNemar's test. [10] [11]
[1] [2] Choosing the right statistical test is not a trivial task. [1] The choice of the test depends on many properties of the research question. The vast majority of studies can be addressed by 30 of the 100 or so statistical tests in use .
Howling winds, cold temperatures and even the chance of heavy snow could be in store for many Americans across the country as they gather for their Thanksgiving feasts next week. Forecasters said ...
In probability theory and statistics, the binomial distribution with parameters n and p is the discrete probability distribution of the number of successes in a sequence of n independent experiments, each asking a yes–no question, and each with its own Boolean-valued outcome: success (with probability p) or failure (with probability q = 1 − p).
Coffee beans are hitting record high prices not seen in nearly 50 years after difficult growing seasons among some of the world's top producing regions. Earlier this week, the Wall Street Journal ...
The test confirmed that the suspect was the father of John Guillot III, or John Guillot Jr., Kirkegaard said. According to authorities, Guillot and Whitney did not know each other.
