How to Find IQR in Google Sheets
Finding the Interquartile Range (IQR) in Google Sheets is a straightforward process that involves a few simple steps. IQR is a measure of statistical dispersion and is calculated as the difference between the third and first quartiles.
This guide will walk you through the necessary steps to compute IQR in Google Sheets using built-in functions. Whether you're managing data for a project or analyzing statistical information, understanding how to calculate IQR can be very beneficial.
Additionally, we will explore why Sourcetable is a better alternative to using Google Sheets, as it helps you become an advanced spreadsheet user faster with its AI-first approach.
How to Find IQR in Google Sheets
To calculate the Interquartile Range (IQR) in Google Sheets, you can follow a few straightforward steps. The IQR is a measure of how spread out the middle 50% of values in a dataset are. It is calculated by subtracting the first quartile (Q1) from the third quartile (Q3).
Step 1: Enter the Data
Start by entering your dataset into a single column in a Google Sheets spreadsheet. Ensure that all relevant data points are included in this column for accurate calculation.
Step 2: Use the QUARTILE() Function
Use the QUARTILE() function to find the first quartile (Q1) and the third quartile (Q3). The syntax for this function is QUARTILE(data, quartile_number) where data is the array of data values and quartile_number indicates the quartile to calculate (1 for Q1 and 3 for Q3).
Step 3: Calculate the IQR
Once you have Q1 and Q3, calculate the IQR by subtracting Q1 from Q3. The formula for this step is simple: IQR = Q3 - Q1. This will give you the interquartile range, representing the middle 50% of your dataset values.
By following these steps, you can efficiently determine the IQR in Google Sheets, allowing for a clear measurement of variability within your dataset.

Frequently Asked Questions
How do you calculate the interquartile range (IQR) in Google Sheets?
Enter your data into one column, use the QUARTILE function to calculate Q1 and Q3, and then subtract Q1 from Q3 to get the IQR. For example, you can use =QUARTILE(A2:A11, 3) - =QUARTILE(A2:A11, 1) to find the IQR.
What is the syntax for the QUARTILE function in Google Sheets?
The syntax for the QUARTILE function is QUARTILE(data, quartile_number), where 'data' is an array of data values and 'quartile_number' is the quartile to calculate (1 for Q1 and 3 for Q3).
Can I use the MEDIAN function to calculate the interquartile range in Google Sheets?
Yes, you can use the MEDIAN function to calculate Q1 and Q3 as an alternative method. The results from using MEDIAN or QUARTILE may vary, but both methods can be utilized to find the IQR.
What formula should I use to find Q1 in Google Sheets?
You can find Q1 in Google Sheets using the formula =QUARTILE(A2:A11, 1).
What formula should I use to find Q3 in Google Sheets?
You can find Q3 in Google Sheets using the formula =QUARTILE(A2:A11, 3).
What steps should I follow to find the IQR in Google Sheets?
First, use the QUARTILE function to find Q1 and Q3. Then, use the formula IQR = Q3 - Q1 to calculate the interquartile range.
What does the quartile_number argument in the QUARTILE function represent?
The quartile_number argument in the QUARTILE function represents the quartile to calculate: use 1 for the first quartile (Q1) and 3 for the third quartile (Q3).
Is there a difference between the results of using the MEDIAN and the QUARTILE functions to calculate the IQR?
Yes, the results from using the MEDIAN function and the QUARTILE function may vary. The QUARTILE function uses the inclusive method to calculate quartiles, while the MEDIAN function may yield a closer result to the manual method.
