Plugging Q1 and Q3 into the formula, we get $$\begin{align*} \text{IQR} &= \text{Q3} - \text{Q1}\\ \text{IQR} &=18-7\\ \text{IQR} &=11 \end{align*} $$ Example Problem 2 - Odd Number of Data Set Values Find the interquartile range of the given data set: ...
Quartiles segment 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 the range gives you the spread of the whole data set, the interquartile range gives...

the 50th percentile (the median) and the 75th percentile. The calculator then subtracts the 75th percentile from the 25th percentile to find the interquartile range using the formula Q3– Q1= IQR. Just type your numbers into the text box and click the “Find the interquartile range” button...
To find the interquartile range, we first need to arrange our values in ascending or descending order. Interquartile range formula Interquartile range = Quartile3 – Quartile1 Ascending order: 2, 21, 24, 33, 41, 45, 47, 67, 71, 75, 105, 204 The next step is to find the values ...

Before finding the interquartilerange in Rlet us look at a simple way to find the interquartile range manually so that you can better understand what the function is doing. To do this, we start by finding the median value. 5 10 12 15 (20) 25 27 30 35 ...
Here,“y”is theunitargument for finding the years between two dates. The DATEDIF function calculates the time range between two values in year/month/day format. Using anampersand(&), we concatenatedyrwith the formula. You can find the time range in months and days. In that case, “m”...
Step 1 –Find the Lower Value Go to cellE5and enter the formula: =MIN(C5:C15) This will find theminimum valuefrom theC5:C15range. Step 2 – Determine the Upper Value Move to cellE11and enter the formula: =MAX(C5:C15) This will find themaximum valuein theC5:C15range. ...
STEP 1: Open your Excel worksheet and identify the dataset range.STEP 2: Select the cell where you want the IQR to appear. For Q1, enter =QUARTILE.INC(A2:A21,1).STEP 3: For Q3, enter =QUARTILE.INC(A2:A21,3).STEP 4: To find the IQR, subtract the Q1 value from the Q3 value....
