quartile- one of the values of a variable that divides the distribution of the variable into four groups having equal frequencies.
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
If a divides b and b divides a then either a is equal to b or a is equal to -b. Additional note: if a divides b, there exist a p such that ap=b. and if b divides a, there exist a q such that a=bq. then ap=(bq)p=b => b(1-pq)=0 => pq=1 since b!=0 => p=q=1 or p=q=-1 => a=b or a=-b
The sum of proportions computed from a frequency distribution must equal
They are all equal . . . they are the same.(In an asymmetric distribution they are not equal.)

A tertile or tercile.
The midpoint of a frequency distribution is the value that divides the distribution into two equal parts. It is calculated by adding the lower and upper limits of a class interval and dividing the sum by 2.
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
A quartile divides a distribution into four equal parts, each containing 25% of the data. The first quartile (Q1) represents the value below which 25% of the data fall, the second quartile (Q2) is the median, and the third quartile (Q3) is the value below which 75% of the data fall.
the middle of something divides it into two equal parts not the center because the center divides it into 4 equal parts
The midsagittal plane divides the right and left sides of the brain into two equal sections. A plane divides the body into two equal sides.
That's right, the 90th percentile is the top 10%.
