The interquartile range (IQR) measures the spread of the middle half of your data. It is the range for the middle 50% of yoursample. Use the IQR to assess the variability where most of your values lie. Larger values indicate that the central portion of your data spread out further. Con...

The interquartile range (IQR) is then calculated as (1.3)IQR=upperquartile−lowerquartile. The IQR and upper and lower quartile values for the student height data are shown plotted onto a dotplot inFig. 1.7. Note that of the 40 data values, 10 are below the lower quartile, 10 are abo...
The interquartile range (IQR) is the difference between the first quartile and third quartile. The formula for this is: IQR = Q3- Q1 There are many measurements of the variability of a set of data. Both therangeandstandard deviationtell us how spread out our data is. The problem with th...
If instead of computing the interquartile range you need to compute a generic percentile, you can try ourpercentile calculator, which will show the percentile calculation with all the steps. Not only visually but outliers can also be detected and found using a formula. The "1.5 times IQR" rul...
Interquartile range of data set is the middle 50% of the data set found between the first and third quartiles. We explain it using examples.
Formula The following is the interquartile range calculation formula: IQR = Q3 - Q1 where: IQR = interquartile range Q3 = third quartile Q1 = first quartile Reference this content, page, or tool as: "Interquartile Range Calculator"at https://miniwebtool.com/interquartile-range-calculator/ fro...
Let us illustrate the information we have in a diagram. The figures we have—the minimum, Q1, the median, Q3, and the maximum value—fit well in a box-and-whisker plot. The interquartile range is the distance between Q1 and Q3, and to calculate this we use the formulaIQRupperquartile...
