QUARTILE
TheQUARTILE
function in Google Sheets is used to calculate quartiles from a given data set. Quartiles divide a dataset into four equal parts. This function can be used to find the value at a given quartile rank or to calculate quartile ranges.

Usage
Use the QUARTILE
formula with the syntax shown below, it has 2 required parameters:
 data (required):
The range of cells containing the data for which you want to calculate the quartiles.  quartile_number (required):
An integer between 0 and 4 representing the quartile number to be calculated. 0 represents the minimum value, 1 represents the first quartile, 2 represents the second quartile (the median), 3 represents the third quartile, and 4 represents the maximum value.
Examples
Here are a few example use cases that explain how to use theQUARTILE
formula in Google Sheets.
Finding the median
To find the median of a dataset, you can use the QUARTILE
function with a quartile number of 2, which represents the second quartile (the median).
Calculating the interquartile range
The interquartile range (IQR) is the range of values between the first and third quartiles. To calculate IQR, you can use the QUARTILE
function twice, once with a quartile number of 1 and again with a quartile number of 3, and then subtract the two results.
Identifying outliers
Outliers are data points that fall outside of the typical range of values in a dataset. To identify outliers, you can use the QUARTILE
function to calculate the first and third quartiles, and then use these values to determine the range of typical values. Any values outside of this range can be considered outliers.
Common Mistakes
QUARTILE
not working? Here are some common mistakes people make when using the QUARTILE
Google Sheets Formula:
Using the wrong quartile number
One common mistake when using the QUARTILE
function is using the wrong quartile number. Make sure you understand which quartile you are trying to calculate and use the correct number (1, 2, 3, or 4).
Including nonnumeric data
The QUARTILE
function only works with numeric data. If you include nonnumeric data in the data range, the function will return an error.
Using the wrong data range
Another common mistake when using the QUARTILE
function is using the wrong data range. Make sure you select the entire range of cells that contains the data set, including any header rows or columns.
Related Formulas
The following functions are similar to QUARTILE
or are often used with it in a formula:

AVERAGE
The AVERAGE function calculates the average (arithmetic mean) of the values passed to it. It is commonly used to find the average of a range of cells containing numerical data.

MEDIAN
The
MEDIAN
function returns the median (middle) value of a set of numbers. It is commonly used to find the middle value in a range of data points. If the number of data points is even, it returns the average of the two middle values. This function can be useful in statistical analysis and data visualization. 
STDEV
The
STDEV
function calculates the standard deviation of a set of numbers. It measures the amount of variation or dispersion of a set of values from the average (mean) value. It is commonly used in statistics to determine the spread of a data set. The values can be supplied as individual cells, ranges, or constants. 
VAR
The
VAR
formula calculates the variance of a set of numerical values. Variance is a measure of how spread out a set of data is in relation to the mean. This formula is commonly used in statistical analysis to measure the variability or diversity of a dataset. 
PERCENTILE
The
PERCENTILE
function returns the value at a given percentile of a dataset. This can be useful in statistics and data analysis when trying to find the value that corresponds to a certain percentile in a set of data.
