In Excel, binomial distributions let you calculate probabilities in two situations. In addition, you should be familiar with the sole hypergeometric distribution function because it is related to binomial functions. You would use binomial distributions in these situations:

  • When you have a limited number of independent trials, or tests, which can either succeed or fail

  • When success or failure of any one trial is independent of other trials

BINOM.DIST: Binomial probability distribution

October 2016 (Note: all the previous publications in the basic statistics category are listed on the right-hand side. Select 'Return to Categories' to go to the page with all publications sorted by category. Select this link for information on the SPC for Excel software.) Last month, distribution fitting was introduced. The following example was used. You need to calculate process capability.

The BINOM.DIST function finds the binomial distribution probability. The function uses the syntax

where number_s is the specified number of successes that you want, trials equals the number of trials you’ll look at, probability_s equals the probability of success in a trial, and cumulative is a switch that’s set to either the logical value TRUE (if you want to calculate cumulative probability) or the logical value FALSE (if you want to calculate the exact probability).

For example, if a publisher wants to know the probability of publishing three best-selling books out of a set of ten books when the probability of publishing a best-selling book is ten percent, the formula is

which returns the value . This indicates that there’s roughly a 6-percent chance that in a set of ten books, a publisher will publish exactly three best-selling books.

  2. EasyFit – Distribution Fitting Made Easy EasyFit helps you deal with uncertainty and make informed decisions by analyzing your probability data and selecting the best fitting distribution. EasyFit allows to easily fit a large number of distributions to your data in seconds, saves time and prevents analysis errors.
  3. What is distribution fitting. Fitting a distribution to a data sample consists, once the type of distribution has been chosen, in estimating the parameters of the distribution so that the sample is the most likely possible (as regards the maximum likelihood) or that at least certain statistics of the sample (mean, variance for example) correspond as closely as possible to those of the.

To calculate the probability that a publisher will publish either one, two, or three bestsellers in a set of ten books, the formula is

which returns the value , which indicates that there is roughly a 99-percent chance that a publisher will publish between one and three bestsellers in a set of ten books.

BINOM.INV: Binomial probability distribution

The BINOM.INV functions find smallest value for which the cumulative binomial distribution equals or exceeds a specified criterion, or alpha, value. The function uses the syntax

where trials equals the number of Bernoulli trials you’ll look at, probability_s equals the probability of success in a trial, and alpha equals the criterion value you want to meet or beat.

If you set the trials to 10, the probability to .5 and the criterion value to .75, for example, the formula is

=BINOM.INV(10,0.5,0.75)

which returns the value 6.

BINOM.DIST.RANGE: Binomial probability of Trial Result

The BINOM.DIST.RANGE function finds the probability of a trial result or a range of trial results for a binomial distribution. The function uses the syntax

where trials equals the number of trials you’ll look at, probability_s equals the probability of success in a trial, number_s sets the number of successful trials, and number_s2 (which is an optional argument) sets the maximum number of successful trials.

If you set the trials to 10, the probability to .5 and the number of successful trials to 3, for example, the formula is

=BINOM.DIST.RANGE(10,0.5,3)

which returns the value 0.11718, meaning the probability of having exactly three successful trials equals roughly 12%.

If you set the trials to 10, the probability to .5 and the number of successful trials to anything from 3 to 10, for example, the formula is

=BINOM.DIST.RANGE(10,0.5,3,10)

which returns the value , meaning the probability of the number of successful trials range anywhere from 3 to 10 equals roughly 95%.

NEGBINOM.DIST: Negative binominal distribution

The NEGBINOM.DIST function finds the probability that a specified number of failures will occur before a specified number of successes based on a probability-of-success constant. The function uses the syntax

where number_f is the specified number of failures, number_s is the specified number of successes, probability_s is the probability of success, and cumulative is a switch you set to 0 or FALSE if you want a cumulative distribution and to 1 or TRUE if you want a probability distribution.

For example, suppose you’re a wildcat oil operator and you want to know the chance of failing to find oil in exactly ten wells before you find oil in exactly one well. Home design software for mac. If the chance for success is 5 percent, you can find the chance that you’ll fail ten times before drilling and finding oil by using the formula

which returns the value 0.016465266, indicating that there’s less than a 2-percent chance that you’ll fail ten times before hitting a gusher.

CRITBINOM: Cumulative binomial distribution

The CRITBINOM function, which is really an old Excel function and available in recent versions of Excel for reasons of backwards compatibility, finds the smallest value for which the cumulative binomial distribution equals or exceeds a criterion value. The function uses the syntax

where trials is the number of Bernoulli trials, probability_s is the probability of success for each trial, and alpha equals your criterion value. Both the probability_s and alpha arguments must fall between 0 and 1.

HYPGEOM.DIST: Hypergeometric distribution

The HYPERGEOMETRIC function returns the probability of a specified number of sample successes. A hypergeometric distribution resembles a binomial distribution except with a subtle difference. In a hypergeometric distribution, the success in one trial affects the success in another trial. Typically, you use the HYPGEOM.DIST function when you take samples from a finite population and don’t replace the samples for subsequent trials. The function uses the syntax

where sample_s equals the specified number of sample successes, number_sample gives the size of the sample, population_s gives the number of successes in the population, number_pop gives the size of the population, and cumulative is a switch which tells Excel to return either a cumulative distribution (indicated with a 1 or TRUE argument value) or a probability density (indicated with a 0 or FALSE argument value).

As an example of a hypergeometric distribution, suppose you want to calculate the probability that in a sample of 30 items, 5 will be successful. Further suppose you know that within a 4,000-item population, 1,000 are successful. You use the following formula to make this calculation:

which returns the value 0.0104596, indicating that the chances that exactly 5 items will be successful in a set of 30 items given the characteristics of the population equals roughly 10 percent.
