When working with large datasets in Google Sheets, understanding how to find percentiles is crucial for data analysis and interpretation. Percentiles help identify the value below which a certain percentage of data points fall, providing valuable insights into data distribution and outliers. In this tutorial, we will explore how to find percentiles in Google Sheets, a powerful tool for data manipulation and visualization.
What are Percentiles?
A percentile is a measure that indicates the value below which a certain percentage of data points fall. For example, the 25th percentile is the value below which 25% of the data points fall, while the 75th percentile is the value below which 75% of the data points fall. Percentiles are essential in understanding data distribution, identifying outliers, and making informed decisions.
Why Find Percentiles in Google Sheets?
Finding percentiles in Google Sheets is essential for various reasons. Firstly, it helps identify the distribution of data, allowing you to understand how values are scattered across the dataset. Secondly, percentiles enable you to detect outliers, which can significantly impact data analysis and interpretation. Finally, percentiles provide a basis for comparison, enabling you to evaluate data against specific benchmarks or standards.
Overview of the Tutorial
In this tutorial, we will cover the following topics:
– Understanding the PERCENTILE function in Google Sheets
– Using the PERCENTILE function to find specific percentiles
– Creating a percentile chart to visualize data distribution
– Tips and best practices for working with percentiles in Google Sheets
By the end of this tutorial, you will be equipped with the knowledge and skills to find percentiles in Google Sheets, enabling you to make informed decisions and drive meaningful insights from your data.
How to Find Percentile in Google Sheets
Google Sheets provides an efficient way to calculate percentiles, which is a crucial statistical measure in data analysis. A percentile is a value below which a certain percentage of data points fall. In this article, we will explore the steps to find percentile in Google Sheets.

Understanding Percentile
A percentile is a measure that indicates the value below which a certain percentage of data points fall. For example, the 25th percentile is the value below which 25% of the data points fall, while the 75th percentile is the value below which 75% of the data points fall.
Methods to Find Percentile in Google Sheets
There are two methods to find percentile in Google Sheets: using the PERCENTILE function and using the PERCENTILE.INC function. The main difference between the two functions is how they handle duplicate values.
Method 1: Using the PERCENTILE Function
The PERCENTILE function is used to calculate the k-th percentile of a range of data. The syntax for the PERCENTILE function is:
| PERCENTILE(range, k) |
| range: The range of data for which you want to calculate the percentile. |
| k: The percentile value you want to calculate (e.g., 0.25 for the 25th percentile). |
For example, if you want to calculate the 25th percentile of the data in the range A1:A10, you can use the formula:
=PERCENTILE(A1:A10, 0.25)
Method 2: Using the PERCENTILE.INC Function
The PERCENTILE.INC function is similar to the PERCENTILE function, but it includes the k-th percentile value in the calculation. The syntax for the PERCENTILE.INC function is:
| PERCENTILE.INC(range, k) |
| range: The range of data for which you want to calculate the percentile. |
| k: The percentile value you want to calculate (e.g., 0.25 for the 25th percentile). |
For example, if you want to calculate the 25th percentile of the data in the range A1:A10, you can use the formula:
=PERCENTILE.INC(A1:A10, 0.25)
Example
Suppose you have a dataset of exam scores in the range A1:A10, and you want to calculate the 25th, 50th, and 75th percentiles. You can use the following formulas: (See Also: How To Lock A Number In Google Sheets)
=PERCENTILE(A1:A10, 0.25)
=PERCENTILE(A1:A10, 0.5)
=PERCENTILE(A1:A10, 0.75)
Alternatively, you can use the PERCENTILE.INC function:
=PERCENTILE.INC(A1:A10, 0.25)
=PERCENTILE.INC(A1:A10, 0.5)
=PERCENTILE.INC(A1:A10, 0.75)
Recap
In this article, we discussed how to find percentile in Google Sheets using the PERCENTILE and PERCENTILE.INC functions. We also explored the difference between the two functions and provided an example to illustrate their use.
Key Points:
- The PERCENTILE function calculates the k-th percentile of a range of data.
- The PERCENTILE.INC function includes the k-th percentile value in the calculation.
- Both functions can be used to calculate percentiles in Google Sheets.
By following these steps and using the PERCENTILE or PERCENTILE.INC function, you can easily calculate percentiles in Google Sheets and gain valuable insights into your data.
Frequently Asked Questions: How to Find Percentile in Google Sheets
What is the formula to find the percentile in Google Sheets?
The formula to find the percentile in Google Sheets is PERCENTILE.EXC(array, k), where “array” is the range of data you want to find the percentile for, and “k” is the percentile value you want to find (e.g. 0.25 for the 25th percentile).
How do I find the 90th percentile in Google Sheets?
To find the 90th percentile in Google Sheets, you can use the formula =PERCENTILE.EXC(A1:A10, 0.9), assuming your data is in cells A1:A10. This will return the value at the 90th percentile of your data.
Can I find the percentile of a specific range of data in Google Sheets?
Yes, you can find the percentile of a specific range of data in Google Sheets. Simply specify the range of cells you want to find the percentile for in the PERCENTILE.EXC formula. For example, =PERCENTILE.EXC(B2:E10, 0.5) would find the 50th percentile of the data in cells B2:E10.
How do I find the percentile of a dataset with multiple columns in Google Sheets?
To find the percentile of a dataset with multiple columns in Google Sheets, you can use the PERCENTILE.EXC formula with the entire range of data, including multiple columns. For example, =PERCENTILE.EXC(A1:C10, 0.75) would find the 75th percentile of the data in cells A1:C10.
Can I use the PERCENTILE.EXC function with filtered data in Google Sheets?
No, the PERCENTILE.EXC function in Google Sheets does not work with filtered data. If you want to find the percentile of filtered data, you will need to copy the filtered data to a new range and then use the PERCENTILE.EXC function on that range.
