Subtract the lower quartile from the upper quartile.

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,

No. The upper quartile, by definition, must be at least as large as the lower quartile.

The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.

lower quartile = 1/4(n+1) upper quartile = 3/4(n+1) where n is the number of the values. Obviously the values have to be ordered from the lower to the higher: the number you'll get is the position in this order. Let's say you get 4 for your lower quartile, it means that the 4th value is your lower quartile.

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?

you do work out the upper and lower quartile

Subtract the lower quartile from the upper 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.

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

the interquartile is just subtracting the high quartile from the low quartile. * * * * * No, it is subtracting the lower quartile from the higher quartile.

25% of the observed values are smaller than the lower quartile.

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.

You would first need to know the amounts of each quartile. Then use your formula to place the numbers inside.

minimum is the lowest number and the lower quartile is the closest number in between the middle number and the minimum quartile
