Quartile coefficient of dispersion. In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and between data sets. The statistic is easily computed using the first ( Q1) and third ( Q3) quartiles for each data set.
Quartile deviation measures the absolute level of dispersion and is not affected by the extreme values. And the relative measure with reference to quartile deviation is known as the coefficient of quartile deviation. Coefficient of Quartile Deviation = (Q 3 – Q 1) / (Q 3 + Q 1)
Quartile coefficient of dispersion = Quartile Deviation/ Mean · Coefficient of variation (C.V) = Standard Deviation /Mean x 100 · Mean Deviation/Mean · Mean ...
Jan 24, 2017 · The sample quartile coefficient of dispersion is defined as. where Q1 is the lower quartile (25-th percentile) and Q3 is the upper quartile (75-th percentile). This statistic has been suggested as a robust alternative to the coefficient of variation. Syntax 1:
In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and between data sets. Since it is based on quantile information, it is less sensitive to outliers than measures such as the Coefficient of variation. As
The Quartile Deviation doesn't take into account the extreme points of the distribution. Thus, the dispersion or the spread of only the central 50% data is ...
Definition: Relative measure of the variable dispersion being the ratio of the quartile deviation and the median of this variable expressed in percent.
Quartile coefficient of dispersion. In statistics, the quartile coefficient of dispersion is a descriptive statistic which measures dispersion and which is used to make comparisons within and between data sets. The statistic is easily computed using the first ( Q1) and third ( Q3) quartiles for each data set.
The Quartile Deviation is a simple way to estimate the spread of a distribution about a measure of its central tendency (usually the mean). Based on the quartile deviation, the Coefficient of Quartile Deviation can be defined, which makes it easy to compare the spread of two or more different distributions.
