Step 1: Order the values in the data set from least to greatest. Step 2: Separate the lower and upper half of the data set into two groups, leaving the median all by itself in the middle. Step 3: Find the 1st and 3rd quartiles in the lower and upper groups, respectively. ...
Method 2 – QUARTILE Function to Find Quartiles of Marks in Excel We have some student marks. Our goal is to find the 3rd quartile of this dataset using theQUARTILEfunction. Steps Use the following formula in cellE5: =QUARTILE(C5:C10,3) PressEnter. Method 3 – Find Quartiles for All t...
Quartilessegment any distribution that’s ordered from low to high into four equal parts. The interquartile range (IQR) contains the second and third quartiles, or the middle half of your data set. Whereas therangegives you the spread of the whole data set, the interquartile range gives yo...
A measure of variability that helps us to find an outlier in a data set. The 25th quartile and 75th quartile in a data set help to find the interquartile range. It also measures the scatters in data. Answer and Explanation:1 First of all, we have to find the value of the First...
In data science find the spread of a data set can often lead to clues about the statistical relationship between the data points. The interquartile range is a useful type of spread since it is not affected much by outlying extremes. The interquartile range of a data set is the difference ...

STEP 3:For Q3, enter=QUARTILE.INC(A2:A21,3). STEP 4:To find the IQR, subtract the Q1 value from the Q3 value. Like this: D2-D1. Press Enter and voilà, your IQR is calculated! And there you have it, you can now measure the statistical spread of your data in seconds. ...
Repeat step 3 to find the median of the upper half (7, 8, 9):[Q1 = 2], 4,[Q2 =6], 7,[Q3 = 8], 9. While the above procedure works, you may want to use the lower and upper quartile formulas for larger data sets.
