NEGBINOM.DIST: Google Sheets Formulas Explained

Have you ever felt like you're drowning in the endless sea of spreadsheets? Well, you're not alone my friend! As a marketer, I know how overwhelming data can be, and that's why I'm here to tell you about one formula that can help: NEGBINOM.DIST. Don't let the long name scare you off, this formula can be your secret weapon.

What is NEGBINOM.DIST?

NEGBINOM.DIST is a statistical function that calculates the probability of a specified number of failures before a specified number of successes in binomial distribution. In simpler terms, it can help you determine the probability of getting a certain number of failures before achieving a specific number of successes in a given situation.

For instance, if you're running a marketing campaign hoping to get 5 sales from your target audience, NEGBINOM.DIST can help you identify the probability of achieving those sales based on previous attempts, while taking into account the potential number of failed attempts.

How to Use NEGBINOM.DIST in Google Sheets

If you're already familiar with the statistical language of excel, using NEGBINOM.DIST will be a breeze. For those new to this concept, there are a few key things to know before diving in. Let's take a look at an example:

=NEGBINOM.DIST(Number_f, Number_s, Probability_s, Cumulative)

The function takes four arguments:

• Number_f: The number of failures you want to predict before achieving the desired number of successes.
• Number_s: The desired number of successes.
• Probability_s: The probability of success in each attempt.
• Cumulative: Logical value that determines the type of probability distribution to use.

Let's take the example mentioned earlier and apply the NEGBINOM.DIST formula. If the probability of success is 10% and you're trying to get 5 sales, you would use the following formula:

=NEGBINOM.DIST(0, 5, 0.1, false)

Breaking down the formula:

• Number_f: 0. You're not considering any failed attempts since you're simply targeting a specific number of successes.
• Number_s: 5. The desired number of successful attempts you're aiming for.
• Probability_s: 0.1. The probability of success in each attempt.
• Cumulative: False. We're not including failed attempts.

The result of this formula will give you the probability of achieving five sales without any failed attempts. You can further manipulate the formula to account for potentially unsuccessful attempts.
