Interquartile range : interquartile range (IQR), also called the midspread, middle 50%, or H‑spread, is a measure of statistical dispersion, being equal to the difference between 75th and 25th ...

The IQR (Inter Quartile Range) method is used for skewed data. It calculates the minimum and maximum values based on the 25th and 75th percentiles (Q1 and Q3). Any value less than the minimum or ...

Finally, we calculate IQR: IQR = Q3 – Q1 = 12 – 4 = 8. In this case, the IQR is 8. This tells us that the central half of this dataset falls between the values of 4 and 12. In conclusion, calculating ...

The interquartile range (IQR) is therefore 18 - 4 = 14. You will notice that the fact there is an outlier in this data (60) which has had no bearing on the calculation of the interquartile range.

Decision based non-linear filtering is widely used for the removal of impulsive noise. Various robust statistical estimators of scale are in use for determining the threshold of the filtering process.
