The interquartile range (IQR), represents the middle 50 percent of a data set. To calculate it, first order your data points from least to greatest, then determine your first and third quartile positions by using the formulas (N+1)/4 and 3*(N+1)/4 respectively, where N is the number...

2. Next, we need to calculate Q3. To calculate Q3 in Excel, simply find an empty cell and enter the formula ‘=QUARTILE(array, 3)‘. Again, replacing the ‘array‘ part with the cells that contain the data of interest. 3. Finally, to calculate the IQR, simply subtract the Q1 value...
So far, this tutorial explained how to compute the Interquartile Range in R. As you have seen, it’s very easy to use the R programming language as an IQR calculator. However, if you want to learn more about the theoretical research concept and the statistical interpretation of the IQR ru...
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...
Learn Excel Interquartile Range calculation to master data variability & enhance analysis. Uncover techniques, interpretation tips, and uses in business decision-making.
Calculate the interquartile range by handThe interquartile range is found by subtracting the Q1 value from the Q3 value:FormulaExplanation IQR = interquartile range Q3 = 3rd quartile or 75th percentile Q1 = 1st quartile or 25th percentile
In this guide, I will show you how to find the interquartile range (IQR) in SPSS. I will also show you how to find the first (Q1) and third (Q3) quartiles.
