Returns the smallest value for which the cumulative binomial distribution is greater than or equal to a criterion value. Use this function for quality assurance applications. For example, use CRITBINOM to determine the greatest number of defective parts that are allowed to come off an assembly line run without rejecting the entire lot.
Important This function has been replaced with one or more new functions that may provide improved accuracy and whose names better reflect their usage. Although this function is still available for backward compatibility, you should consider using the new functions from now on, because this function may not be available in future versions of Excel.
For more information about the new function, see BINOM.INV function.
The CRITBINOM function syntax has the following arguments (argument: A value that provides information to an action, an event, a method, a property, a function, or a procedure.):
- Trials Required. The number of Bernoulli trials.
- Probability_s Required. The probability of a success on each trial.
- Alpha Required. The criterion value.
- If any argument is nonnumeric, CRITBINOM returns the #VALUE! error value.
- If trials is not an integer, it is truncated.
- If trials < 0, CRITBINOM returns the #NUM! error value.
- If probability_s is < 0 or probability_s > 1, CRITBINOM returns the #NUM! error value.
- If alpha < 0 or alpha > 1, CRITBINOM returns the #NUM! error value.
The example may be easier to understand if you copy it to a blank worksheet.
How do I copy an example?
- Select the example in this article. If you are copying the example in Excel Online, copy and paste one cell at a time.
Important: Do not select the row or column headers.
