These are pure numbers independent of the units of measurement and used to compare two or more sets of data values. For example, when rainfall data is made available for different days in mm, any absolute measures of dispersion give the variation in rainfall in mm. What are Absolute Dispersion and Relative Dispersion Absolute & relative dispersion are two different ways to measure the spread of a data set.They are used extensively in biological statistics, as biological phenomena almost always show some variation and spread. Absolute and Relative measures of Dispersion. Lets look at the first of the relative measures of dispersion. As the name suggests, the measure of dispersion shows the scatterings of the data. These quantities measures the dispersion in the same units as the units of original data. It is the difference between the greatest observation and the smallest observation. Big clawsc. Absolute dispersion is the dispersion which are defined in same units in which original data is presented. …, 9. This is given by (H – L)/(H + L). Absolute measures of dispersion include: The range, The quartile deviation, The mean deviation, The standard deviation and variance. These quantities measures the dispersion in the same units as the units of original data. Absolute measures are dependent on the unit of the variable under consideration whereas the relative measures of dispersion are unit free. Relative measures … Absolute measures of Dispersion are expressed in same units in which original data is presented but these measures cannot be used to compare the variations between the two series. b)extended object.​. In this method, the difference between the upper quartile and lower quartile is taken and is called the interquartile range. • Relative Measures of Dispersion: Relative measures of dispersion, are also known as coefficients of dispersion, are obtained as ratios or percentages. But range does not provide a sufficient picture about the dispersion. For our example data set, it would be the ratio (18 – 2)/(18 + 2), so (16/20) or 4/5. Relative measures of dispersion are calculated as ratio or percentages; for instance, one relative measure, of dispersion is the ratio of … relative dispersion / absolute dispersion are two different ways to measure the spread of a data set.
