Un viaje a través de este increíble mundo matemático
Name origin ď‚ž
The German term Statistik, introduced by Gottfried Achenwall in (1749), was refering to the analysis of information of the State, that is to say, the " Science of the State ". Also it was called a political arithmetic. It was not up to the 19th century when the term statistics acquired the meaning of gathering and classifying information. This concept was introduced by the Britisher John Sinclair (1754-1835). In his origin, therefore, the Statistics was associated with the States or free cities, to be used by the government. The collection of information brings over of conditions and localities continues across the national and international services of statistics. Especially, the censuses began to supply regular information it brings over of the population of every country.
Statistical parameters ď‚ž
The measures of central are the following ones: The arithmetic mean, usually used for calculating the middle part of some measure units. This is the formula:
ď‚ž
The medium arithmetic (Me) is the middle datum of one statistical parameter, and the fad (Mo) , which represent the most repeated datum of the succession.
The scattering measurements are: The variance, which is the average of the squares of the distances from the mean. Calculated with this formula:
The standard deviation, which is the hope of the square of the deviation of that variable from its mean, and this is the formula:
The coefficent of variation is used to compare the dispersion of two heterogeneous populations. This is the formula:
Graphic interpretation ď‚ž
We usually use graphics for a better interpretarion of this statistical parameters, like graphics histograms, pie charts, barcharts, etc‌.. Like we can appreciate in these photos:
