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 you the range of the middle half of a data set....
The box and whisker plot gives us a visual of how data is distributed. The “box” represents the interquartile range, indicating where the middle fifty percent of the data lies. On either end of the box, you’ll find the first (lower) quartile (the 25% mark) and the third (upper)...
As a rule of thumb, values with a z score greater than 3 or less than –3 are often determined to be outliers.Using the interquartile rangeThe interquartile range (IQR) tells you the range of the middle half of your dataset. You can use the IQR to create “fences” around your data...

Boxplots are drawn as a box with a line inside of it, and has extended lines attached to each of its sides (known as “whiskers”). The box is used to represent the interquartile range (IQR) — or the 50 percent of data points lying above the first quartile and below the third ...
Box and whisker plot is the process to abstract a set of data, which is estimated using an interval scale. Visit BYJU’S to learn the procedure of drawing box plots and whisker plots.
For a symmetric distribution (so the median equals themidhinge, the average of the first and third quartiles), half the IQR equals themedian absolute deviation(MAD). Themedianis the corresponding measure ofcentral tendency. Boxplot(with an interquartile range) and aprobability density function(pd...

How do outliers relate to the Inter-Quartile Range? TheIQRis the length of the box in your box-and-whisker plot. An outlier is any value that lies more than one and a half times the length of the box from either end of the box. ...
How to Find Outliers Using theInterquartile Range(IQR) An outlier is defined as being any point of data that lies over 1.5 IQRs below the first quartile (Q1) or above the third quartile (Q3)in a data set. High = (Q3) + 1.5 IQR Low = (Q1) – 1.5 IQR ...
