WEIBULL.DIST: Google Sheets Formulas Explained

Hey there! Are you a spreadsheet enthusiast just like me? If yes, then you've probably been using Google Sheets to perform various mathematical and financial operations. But have you ever heard of the WEIBULL.DIST formula? No? Don't worry! Just keep reading to find out all you need to know about WEIBULL.DIST and how to use it on Google Sheets like a pro.


In simple terms, WEIBULL.DIST is a statistical formula used to calculate the probability distribution of a set of data points. It is mainly used to analyze the reliability of machines and products, the lifetime of batteries, and other similar scenarios.

The WEIBULL.DIST formula takes four arguments:

  • X - the value you want to evaluate.
  • Alpha - the shape parameter of the distribution.
  • Beta - the scale parameter of the distribution.
  • Cumulative - a logical value that determines the form of the function. True evaluates the cumulative distribution function while False evaluates the probability density function.

Here's an example: suppose you want to analyze the lifetime of a batch of batteries used in your company. You record the lifetime of each battery in days, and you want to know the probability that a battery will last at least a certain number of days. You can use the WEIBULL.DIST formula to calculate this probability.

How to Use WEIBULL.DIST on Google Sheets

Now that we understand what WEIBULL.DIST is let's delve into how it is used in Google Sheets. Using WEIBULL.DIST on Google Sheets is easy, you just need to know the right syntax. Here is the formula:

=WEIBULL.DIST(X, Alpha, Beta, Cumulative)

And here is how to use it.

Step 1: Open a Google Sheet

First things first, you need to open a Google Sheet. If you don't have one yet, just create a new one from your Google Drive.

Step 2: Enter the Data

Now you need to enter the data you want to analyze. For our battery example, you'd enter the lifetime of each battery in days.

Step 3: Enter the WEIBULL.DIST Formula

Next, enter the WEIBULL.DIST formula. In this case, you want to know the probability that a battery lasts at least a certain number of days. Suppose that number is 100 days. Here's what the formula would look like:

=WEIBULL.DIST(100, Alpha, Beta, True)

The X argument is 100 because that's the number of days we want to evaluate. You'd need to replace Alpha and Beta with the values that apply to your data. The Cumulative argument is set to true because we want to calculate the cumulative distribution function.

Step 4: Hit Enter

Once you've entered the formula, hit the Enter key on your keyboard. You should see the probability distribution of your data based on the values you've entered.

Final Thoughts

WEIBULL.DIST is a powerful statistical formula that can help you analyze the reliability of machines and products, the lifetime of batteries, and other similar scenarios. Using it on Google Sheets is easy and straightforward once you understand the syntax. Don't hesitate to try it out for yourself!
