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. The logic for why the kurtosis statistic measures outliers (rare, extreme observations in the case of data; potential rare, extreme observations in the case of a pdf) rather than the peak is actually quite simple. It gives us an idea about the extent to which individual items vary from one another and from the central value. A measure of statistical dispersion is a nonnegative real number that is zero if all the data are the same and increases as the data become more diverse. MeanFor Grouped data The mean for grouped data is givenbyX = fXifMeanadvantages/disadvantages Advantages It summarizes the entire distribution It could be processed further into thestandard distribution It is unbiased/meaning it always gives usthe population mean Mean Disadvantages It may be some distance from the majorityof observations Can be misleading It is approximated for grouped data Sometimes the figure obtained is notanywhere in the distribution. Two distributions may have same Mean, Median and Mode but the variability among the … and Measures of Dispersion or Variability. 1.4 Measures of dispersion 1.4.1 Range 1.4.2 Semi-interquartile range 1.4.3 Mean deviation 1.4.4 Standard deviation 1.2.5 Geometric mean 1.5 Absolute and relative measure of dispersion … In simple terms, it shows how squeezed or scattered the variable is.
