BINOM.INV

The BINOM.INV function in Google Sheets is a statistical function used to calculate the inverse of the cumulative distribution function for a binomial distribution. It is commonly used in probability and statistics to determine the number of successes required to achieve a specific probability. Learn how to use this function effectively with our comprehensive guide.

Function Syntax and Parameters

Syntax: BINOM.INV(num_trials, prob_success, target_prob)

Parameters:

• num_trials: The number of trials in the binomial distribution.
• prob_success: The probability of success in each trial.
• target_prob: The target probability for which to calculate the number of successes.

Step-by-Step Tutorial

1. Using BINOM.INV to calculate the number of successes:
   • Example: Assuming num_trials is 10, prob_success is 0.5, and target_prob is 0.8, the formula =BINOM.INV(10, 0.5, 0.8) will return the number of successes required to achieve a probability of 0.8.

Use Cases and Scenarios

1. Quality Control: Determine the number of defective products that can be expected in a sample.
2. Risk Analysis: Calculate the number of successful outcomes needed to achieve a desired level of confidence.
3. Hypothesis Testing: Determine the number of successes required for a significant result in a binomial experiment.
