What is the formula for coefficient of quartile deviation?
coefficient of quartile deviation: (Q3-Q1)/(Q3+Q1)
Relation between quartile deviation and mean deviation?
mean deviation =(4/5)quartile deviation
What is the purpose of quartile deviation?
In a data sample, the purpose of quartile deviation is a way to measure data dispersion instead of using the range. The quartile deviation is found by subtracting the lower quartile from the upper quartile, and dividing this result by two.
Example of quartile deviation?
7,8,9 q.d?
How do you determine Q1 and Q3 in quartile deviation?
6,6,9,5,8,9,6,7,8,8,6,5,5,6,8,5,7,7,8,6,5,9,10,14,5,8,5,8,10,10,7,7,7,8,6,6,7,5,7,8,8,5,6,6,7,7,7,6,6,9
What is the formula for coefficient of quartile deviation?
coefficient of quartile deviation: (Q3-Q1)/(Q3+Q1)
If q1q2q3 are three quartiles then Coefficent of quartile deviation is?
coefficient of quartile deviation is = (q3-q1)/(q3+q1)
Quartile deviation advantages disadvantages?
advantages of quartile deviation
Relation between quartile deviation and mean deviation?

What is quartile deviational?
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?
What is relative measure?
These measures are calculated for the comparison of dispersion in two or more than two sets of observations. These measures are free of the units in which the original data is measured. If the original data is in dollar or kilometers, we do not use these units with relative measure of dispersion. These measures are a sort of ratio and are called coefficients. Each absolute measure of dispersion can be converted into its relative measure. Thus the relative measures of dispersion are:Coefficient of Range or Coefficient of Dispersion.Coefficient of Quartile Deviation or Quartile Coefficient of Dispersion.Coefficient of Mean Deviation or Mean Deviation of Dispersion.Coefficient of Standard Deviation or Standard Coefficient of Dispersion.Coefficient of Variation (a special case of Standard Coefficient of Dispersion)
Is the ratio of quartile deviation to mean deviation is raw?
yes
If quartile deviation is 24. find mean deviation and standard deviation?
