When should you throw out an outliers?
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.
What quartile rage difference of the upper and lower quartiles?
There is no need to lose your rag!It is the inter-quartile range.
What does the box in a box-and-whisker plot represent?
The inter-quartile range.
What do you call the difference between the 1st and 3rd quartiles?
The inter-quartile range.
How do you find the inter-quartile of 7 numbers?
The interquartile range is the difference between the Lower quartile and the upper quartile. Obviously you need to be able to find these values. Haylock (2006) explains how to do this for difficult size groups in mathematics explained for primary teachers. He explains the position of the lower quartile is a quarter of (n+1) and that of the upper quartile is three-quarters of (n+1). So for a group of 7 numbers, you find a quarter of 8, which is 2. Therefore the number in second place is the lower quartile. Three quarters of 8 is 6 and so the number in 6th position is the upper quartile. Now take the lower quartile from the upper quartile.
What is the math term for IQR?
IQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile RangeIQR = Inter Quartile Range
How do you find the inter quartile range?
Subtract the lower quartile from the upper quartile.
How do you finde iqr?
IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.
Inter quartile range?
the interquartile is just subtracting the high quartile from the low quartile. * * * * * No, it is subtracting the lower quartile from the higher quartile.

The inter-quartile range.
How do you find the inter quartile?
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
Can the inter quartile range be zero?
Yes, if you have a distribution with very little spread.
What do you call the difference between the 1st and 3rd quartiles?
The inter-quartile range.
What does 2 mean when the means 0?
It is not possible to answer without any information on the spread (range, inter-quartile range, mean absolute deviation, standard deviation or variance).
What can easily be seen on a box-and-whisker plot?
From left to right, Minimum, Lower Quartile, Median, Upper Quartile and Maximum. You can also see the inter-quartile range, and whether the distribution is symmetrical or has a positive or negative skew.
