Abstract

Media, along with median and mode, is the system of central trend indicators. They are usually placed in the central area of the moderately asymmetric one-dimensional distributions, which gives them a high degree of significance, representativeness, with a special importance in the practice of statistical analysis. The main types of medium are: artistic, harmonic, square, geometric and chronological. Each of these environments has two variants: simple and weighted. Position indicators that characterize a series of one-dimensional distribution (the most common in economic statistics) are: - median; - module. With respect to the series after the value of the receipts, following the application of the algorithm, the semidoms of the frequencies is 40and therefore the median interval will be [258, 263). The modal interval is the interval that corresponds to the highest frequency as the value and therefore for the series after the amount of the proceeds earned, it will be [258, 263].
