The vertical edge on the left of the box marks the lower (1st) quartile. The vertical edge on the right of the box marks the upper (3rd) quartile. The median (or 2nd quartile) is indicated by the vertical line in the middle of the box. The box may be drawn vertically in which case the bottom of the box is the lower (1st) quartile, the top of the box is the upper (3rd) quartile and the band in the middle is the 2nd quartile (or median). The whiskers on the end of the box vary.
A number does not have a quartile, a set of data does. The lower quartile of a set of data set is a value, in the data set, such that a quarter of the date set are smaller and three quarters are larger. The upper quartile is defined similarly. The middle quartile, better known as the median, divides the data set in two.
median or middle
Quartile Deviation (QD)The quartile deviation is half the difference between the upper and lower quartiles in a distribution. It is a measure of the spread through the middle half of a distribution. It can be useful because it is not influenced by extremely high or extremely low scores. Quartile Deviation is an ordinal statistic and is most often used in conjunction with the median.why we calculating quartile deviation?
The middle number in the upper half will be three-quarters of the way up and is known as the upper quartile.
Consider the data: 1, 2, 2, 3, 4, 4, 5, 7, 11, 13 , 19 (arranged in ascending order) Minimum: 1 Maximum: 19 Range = Maximum - Minimum = 19 - 1 = 18 Median = 4 (the middle value) 1st Quartile/Lower Quartile = 2 (the middle/median of the data below the median which is 4) 3rd Quartile/Upper Quartile = 11 (the middle/median of the data above the median which is 4) InterQuartile Range (IQR) = 3rd Quartile - 1st Quartile = 11 - 2 = 9

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.
the interquartile is just subtracting the high quartile from the low quartile. * * * * * No, it is subtracting the lower quartile from the higher quartile.
By definition yes. The median is the number which is exactly in the middle of a set of numbers. The first quartile is the point where 25% of the numbers are to the left, and 75% of the numbers are to the right.
The middle number in the upper half will be three-quarters of the way up and is known as the upper quartile.
Subtract the lower quartile from the upper quartile.

IQR = Inter-Quartile Range = Upper Quartile - Lower Quartile.
