- Click an empty cell somewhere on the sheet. For example, click cell B1.
- Type “=QUARTILE(A1:A10,1)” and then press “Enter”. This finds the first quartile. To find the third quartile, type “=QUARTILE(A1:A10,3)”.
What is the difference between quartile and quartile EXC?

How do you find Q1 Q2 Q3 in Excel?
Calculating Interquartile Range Excel
- Select the cell, where we want to get the value of Q1. Then type =Quartile(array,1).
- Now, calculate the value of Q3 the same way. Use the same formula, type =Quartile(array,3).
- Now, select the cell where you want to display the value or IQR in excel.
- You can use a much faster way.
How do you calculate 75th percentile in Excel?
Enter the following formula into the cell, excluding quotes: “=PERCENTILE. EXC(A1:AX,k)” where “X” is the last row in column “A” where you have entered data, and “k” is the percentile value you are looking for.
How do you solve for quartiles?
How to Calculate Quartiles
- Order your data set from lowest to highest values.
- Find the median. This is the second quartile Q2.
- At Q2 split the ordered data set into two halves.
- The lower quartile Q1 is the median of the lower half of the data.
- The upper quartile Q3 is the median of the upper half of the data.
When should I use quartile EXC?
It will return the quartile of a given data set based on percentile values from 0.1, exclusive. The function bases its calculation on a percentile range of 0 to 1, exclusive. As a financial analyst, QUARTILE. EXC can be used to find out a specific percentage of incomes in a population.

The two most common methods for calculating interquartile range are the exclusive and inclusive methods. The exclusive method excludes the median when identifying Q1 and Q3, while the inclusive method includes the median as a value in the data set in identifying the quartiles.
What is the difference between percentile EXC and percentile Inc?
PERCENTILE. INC includes the full range of 0 to 1 as valid k values, compared to PERCENTILE. EXC which excludes percentages below 1/(N+1) and above N/(N+1). Note: Microsoft classifies PERCENTILE as a “compatibility function”, now replaced by the PERCENTILE.
How do you calculate Q1 Q2 Q3 q4?
Quartile Formula:
- Formula for Lower quartile (Q1) = N + 1 multiplied by (1) divided by (4)
- Formula for Middle quartile (Q2) = N + 1 multiplied by (2) divided by (4)
- Formula for Upper quartile (Q3) = N + 1 multiplied by (3) divided by (4)
- Formula for Interquartile range = Q3 (upper quartile) – Q1 (lower quartile)
