What a quartile?
quartile- one of the values of a variable that divides the distribution of the variable into four groups having equal frequencies.
What is quartiles?
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 a is equal to b?
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
What is the sum of proportions computed from a frequency distribution have to equal?
The sum of proportions computed from a frequency distribution must equal
What is the relationship among the mean median and mode in a symmetric distribution?
They are all equal . . . they are the same.(In an asymmetric distribution they are not equal.)
What value which divides the data into one hundred equal parts?
A percentile.
What is one of the values of a variable which divides the distribution of the variables into four groups having equal frequencies?
quartile

What a quartile?
quartile- one of the values of a variable that divides the distribution of the variable into four groups having equal frequencies.
What is one of the values of a variable which divides the distribution of the variables into three groups having equal frequencies?
A tertile or tercile.
What is the mid point of a frequency?
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.
What is quartiles?
The quartile deviation(QD) is half the difference between the highest and lower quartile in a distribution.
One of the values of a variable which divides the distribution of the variable into four groups having equal frequency?
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.
A point that divides a segment into two equal parts?
the middle of something divides it into two equal parts not the center because the center divides it into 4 equal parts
What plane divides the brain into equal left and right sides?
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.
Does 90th percentile equal top 10 percent?
That's right, the 90th percentile is the top 10%.
