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.

What is a lower quartile?
A lower quartile i s the mediaon of the lower half of a data set. A data set is divided up into different quartiles.
What is the upper and lower quartile?
The upper quartile, for a set of ordinal observations, is a value such that a quarter of the observations have a greater value. Similarly, the lower quartile is a value such that a quarter of the observations have a smaller value.
What is the difference between the upper quartile and the lower quartile called?
Interquartile Range, or IQR
What is the median of the lower half of a set of numbers?
The lower quartile.
What is the lower quartile on a box and whisker plot?
The lower quartile is the line that represents the left-hand edge of the "box", in the box and whisker plot.
What does lq stand for?
lower quartile(this is for math)
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 does lower quartile mean in math?
It means the bottom quarter, or bottom 25%
What does quartile in math?
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,
Who do you work out the upper and lower quartile?
you do work out the upper and lower quartile
How do you find the inter quartile range?
Subtract the lower quartile from the upper quartile.
How do you solve 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.
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
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.
What are characteristics of lower quartile?
25% of the observed values are smaller than the lower quartile.
How do you finde iqr?
IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.
Can interquartile range be used for any data eg data below the lower quartile to find if the data is spread out or close together or must we use the lower quartile for data below the lower quartile?
No, interquartile range cannot be for any data. The lower quartile for data must be used below the lower quartile.
