Because the IQR excludes values which are lower than the lower quartile as well as the values in the upper quartile.

Can the interquartile range be greater than the range?
No, since range is max-min and IQR is Q3-Q1. Q1 must be greater than the max and Q3 must be less than the min.
What is the difference between the upper quartile and the lower quartile called?
Interquartile Range, or IQR
What does the Interquartile range tell you about the data set?
It tells you that middle half the observations lie within the IQR.
What is resistant measure?
Ohms
What is the range of this data set 64 76 46 88 88 43 99 50 55?
for the data set shown below find the interwar range IQR. 300,280,245,290,268,288,270,292,279,282
Can the interquartile range be greater than the range?
No, since range is max-min and IQR is Q3-Q1. Q1 must be greater than the max and Q3 must be less than the min.
Is it ever possible for the iqr to be larger than the range?
No, it is not possible.
Does an outlier have a greater effect on the standard deviation or interquartile range?
On the standard deviation. It has no effect on the IQR.
What is the math term for IQR?
IQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile Range
How do you finde iqr?
IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.
What is an outlier when finding the median?
an outlier can be found with this formula... Q3-Q1= IQR( inner quartile range) IQR*1.5=x x+Q3= anything higher than this # is an outlier Q1-x= anything smaller than this # is an outlier
What does IQR mean in math?
The interquartile range (IQR) is a measure of variability, based on dividing a data set into quartiles. Quartiles divide a rank-ordered data set into four equal parts.
How do you find the IQR of a set of data?
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.
How does finding the IQR hep you identify the variability of set of data?
The IQR gives the range of the middle half of the data and, in that respect, it is a measure of the variability of the data.
What is the interquartile range of a number?
the IQR is the third quartile minus the first quartile.
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.
What is the difference between the upper quartile and the lower quartile called?
Interquartile Range, or IQR
