It's statistics: If you have a sorted list of numbers, the lower quartile is the number that is one quarter from the start of the list.
Or you can say that it's the number where one quarter of the entries in the list is smaller than or equal to that number.
lower quartile(this is for math)
The interquartile range of a set of data is the difference between the upper quartile and lower quartile.
It means the bottom quarter, or bottom 25%
Quartiles in statistics are three values such that the lower quartile, second quartile (better known as the median) and upper quartile divide up the set of observations into four subsets with equal numbers in each subset.a quarter of the observations are smaller than the lower quartile,a quarter of the observations are between the lower quartile and the median,a quarter of the observations are between the median and the upper quartile, anda quarter of the observations are greater than the upper quartile,
you do work out the upper and lower quartile
Subtract the lower quartile from the upper quartile.
25% of the observed values are smaller than the lower quartile.
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 interquartile is just subtracting the high quartile from the low quartile. * * * * * No, it is subtracting the lower quartile from the higher 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
IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.
No, interquartile range cannot be for any data. The lower quartile for data must be used below the lower quartile.
