Non-examples of quartiles include values that do not divide a dataset into four equal parts, such as the mean or median, which represent central tendencies rather than specific data divisions. Additionally, any arbitrary number that does not correspond to the 25th, 50th, or 75th percentiles of a dataset is also a non-example. For instance, using the maximum or minimum values of a dataset would not be considered quartiles.
If the result is 1.5 x Inter Quartile Range (or more) above the Upper Quartile or 1.5 x Inter Quartile Range (or more) below the Lower Quartile.
you do work out the upper and lower quartile
It is the upper quartile minus the lower quartile.
values that divide a list of numbers into quaters is called a quartile.
the IQR is the third quartile minus the first quartile.
the interquartile is just subtracting the high quartile from the low quartile. * * * * * No, it is subtracting the lower quartile from the higher quartile.
Subtract the lower quartile from the upper quartile.
IQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile Range
IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.

What is coefficient of quartile deviation?
The second quartile.
In a data sample, the purpose of quartile deviation is a way to measure data dispersion instead of using the range. The quartile deviation is found by subtracting the lower quartile from the upper quartile, and dividing this result by two.
A quartile is 1/4 or 25% of the total. So if you the population is 24 (say in a classroom), then a quartile is 6. Sort the grades lowest to highest, then the bottom 6 are in the lower quartile. The grade for #6 is the lower quartile.
The first quartile, or the lower quartile, is the value such that a quarter of the observations are smaller and three quarters are larger.The third quartile, or the upper quartile, is the value such that three quarters of the observations are smaller and a quarter are larger.
advantages of quartile deviation
A quartile of the population is poor
