The BETADIST function in Google Sheets is a statistical function used to calculate the cumulative beta distribution for a given value. It is commonly used in hypothesis testing and in determining probability values for beta distributions. Learn how to use this function effectively with our comprehensive guide.
Parameters
value: The value at which you want to evaluate the distribution.alpha: The alpha parameter of the beta distribution.beta: The beta parameter of the beta distribution.lower_bound: The lower bound of the distribution.upper_bound: The upper bound of the distribution.

Using the
BETADISTfunction in hypothesis testing:- Example: If you have a sample with 50 successes and 100 failures, and you want to determine the probability of success, you can use
=BETADIST(0.5, 50, 100, 0, 1).
- Example: If you have a sample with 50 successes and 100 failures, and you want to determine the probability of success, you can use
