IQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile Range
Iqr stands for inter quartile range and it is used to find the middle of the quartiles in a set of data. To find this, you find the lower quartile range and the upper quartile range, and divide them both together.
interquartile range is upper quartile (or quartile 3) minus lower quartial ( or quartial 1 ) For example the quartile 3 is 165 and the quartile 1 is 125. The interquartile range is 40. You can go online and see pages. Thank you
Yes, if you have a distribution with very little spread.
the range is also known as the IQR or inner quartile range's. The inter quartile range is the difference between the upper quartile and the lower quartile.heresy a good example.Example:18 27 34 52 54 59 61 68 78 82 85 87 91 93 100~First find the median -----> 68~then the lower quartile --> 52~next the upper quartile --> 87after you find these you may subtract the lower quartile (aka UQ) from the upper quartile (aka the UQ)In our case the IQR = 87 - 52 = 35.
