Can IQR be negative?
No. The upper quartile, by definition, must be at least as large as the lower quartile.
What is the definition to box and whisker plot?
A data display that organizes data values into four parts using the lower extreme,lower quartile,median,upper quartile,and upper extreme.
What is upper quartile?
The upper quartile is the 75% point of the variable. That is, it is the point with 75% of the observations below it and 25% of the observations above it. The upper quartile is the upper 25% of the data.
How do you find the inter quartile range?
Subtract the lower quartile from the upper quartile.
What is the definition for upper extreme in mathematics?
the greatest number of a set of data

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 Definition of lower quartile?
in a set as such {2,3,4,5,6,7,8,}, 5 would be the median, 7 would be the upper quartile, and 3 would be the lower quartile. The lower quartile divides the lower half of a set of data into two equal parts
Who do you work out the upper and lower quartile?
you do work out the upper and lower quartile
What is upper quartile?
The upper quartile is the 75% point of the variable. That is, it is the point with 75% of the observations below it and 25% of the observations above it. The upper quartile is the upper 25% of the data.
The upper quartile of the data set?
the upper quartile is the median of the upper half of a set of data. ;p
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.
What is the interquartile range equal to?
It is the upper quartile minus the lower quartile.
What is the definition for upper extreme in mathematics?
the greatest number of a set of data
What does a box and whisker chart show?
It shows the minimum, lower quartile, median, upper quartile and maximum of a set of observations. It may show outliers separately.It shows the minimum, lower quartile, median, upper quartile and maximum of a set of observations.
