If a set of data are ordered by size, then the lower quartile is a value such that a quarter of the data are smaller than it. The upper quartile is a value such that a quarter of the data are larger than it. Interquartile means between the quartiles.

What is considered measures of variabilty is it mean interquartile range or mean absolute deviation?
interquartile range or mean absolute deviation.
What is the definition of the interquartile in math?
The lower quartile of a data set is the value such that a quarter of the observations are less than or equal to it, and three quarters are larger. The upper quartile is the value such that three quarters of the observations are less than or equal to it, and a quarter are larger. Interquartile refers to between these two numbers.
Is the interquartile range or IQR is found by subtracting the mean from the maximum value of a data set?
No. The IQR is found by finding the lower quartile, then the upper quartile. You then minus the lower quartile value from the upper quartile value (hence "interquartile"). This gives you the IQR.
Does the outlier affect the interquartile?
No. The IQR is a resistant measurement.

Does there have to be an interquartile in math?
Yes, there does.
What is the meaing of interquartile range in math?
The interquartile range of a set of data is the difference between the upper quartile and lower quartile.

What is interquartile range?
An interquartile range is a measurement of dispersion about the mean. The lower the IQR, the more the data is bunched up around the mean. It's calculated by subtracting Q1 from Q3.
What does interquartile range mean?
The interquartile range is the upper quartile (75th percentile) minus (-) the lower percentile (75th percentile). The interquartile range uses 50% of the data. It is a measure of the "central tendency" just like the standard deviation. A small interquartile range means that most of the values lie close to each other.

what is the interquartile range of 16,17,19,22,23,25,27,36,38,40,40,45,46
What is the equation of interquartile deviation?
Interquartile deviation Qd=(q3-q1) / 2
What is the definition of the interquartile in math?
The lower quartile of a data set is the value such that a quarter of the observations are less than or equal to it, and three quarters are larger. The upper quartile is the value such that three quarters of the observations are less than or equal to it, and a quarter are larger. Interquartile refers to between these two numbers.
Why is the interquartile range a more appropriate measure for spread than the range?
the interquartile range is not sensitive to outliers.
What are the common measures of dispersion?
Range, standard deviation, variance, root mean square, interquartile range
Is the interquartile range or IQR is found by subtracting the mean from the maximum value of a data set?
No. The IQR is found by finding the lower quartile, then the upper quartile. You then minus the lower quartile value from the upper quartile value (hence "interquartile"). This gives you the IQR.
