Cross-correlation analysis of the productivity of sugar beets and factors, that it is formed

     Tables are given 4 testify to the presence of direct connection between the probed signs, that with the increase of output of calves the level of yield is increased.

     With the increase of level of output of calves in economies And group as compared to economies ІV groups on 95,44% ( ), the level of yield was increased on 92,45% ( ). 

 

     

     2.3. Distributing rows and them graphic image

     At the statistical grouping of information every group is characterized the system of indexes which have complete connection and interdependence with a groups sign. If the selected groups characterize the not system of indexes, but only by the amount of units which behave to every group, reach distributing rows.

     A distributing row is grouping of units of aggregate on one sign. If an attributive sign is fixed in basis of distributing row, a row is named attributive. If a distributing row is formed on a quantitative sign, he is named variation.

     The variation rows of distributing consist of two elements - variants and frequencies. Variants are name the separate values of групувальної sign.  Frequencies are numbers which show, how many times those are or other variants in the row of distributing.

     Poligon of distributing is built in the rectangular system of co-ordinates, here on wasp of abscissas put aside variant, and on wasp of ordinates is frequency. By the ground of distributing, graphicly represent discrete variation rows. 

     

     For the graphic image of interval variation rows more frequent utillize histograms. The order of construction of this type of the graphs is such: on wasp of abscissas variants put aside the intervals of values. They are bases of rectangles the height of which (ordinate) is proportional frequency of intervals. 

     

     At the image of variation row with the accumulated frequencies the so-called curve of sums turns out in the rectangular system of co-ordinates - Kumulyatu. Kumulyatu apply at comparison of different variation rows, and also in economic researches, in particular for the analysis of concentration of production. 

     

           Like Kumulyatu in the rectangular system of co-ordinates build Ogivu. A difference of the graph is only in that on abscise an axis inflict story frequencies, and on a y-axis - value variant. 
 

       
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 

                       2.4. Summarizing the indexes of distributing rows

     In an order to know about distributing of indexes, there is a necessity of calculation of descriptions of statistical rows of distributing. Major description of variation row of distributing is an average.

     An average in statistics is name summarizing description of aggregate of the of the same type phenomena from any variation sign, which shows the level of sign, counted on unit of aggregate. Together with the method of groupings averages in statistics are one of basic methods of working and analysis of mass data.

     Average as category of statistics - it, from one side, an index, which represents objectively existent properties of the public phenomena which middle indexes can be calculated on the basis of, is real; and from the second - in it взаємознищуються individual divergences of many sizes of the same kind.

     A few types of averages are used in statistics. All of them belong to the class of middle of degree, the general formula of which has such kind:                              

      ,

                                   

     If т = 1, middle arithmetic -  ;

     If т = 2, middle quadratic -  ; 

      If т =  -1, middle harmonious  - ;

     If m=0, middle geometrical   - ,

     Where К₁, К₂, ….К_n – chain coefficients of dynamics.

     Except for the averages of degree, descriptive descriptions of row of distributing of sign are used in statistics — Moda (Мо) and Mediana (Ме).

     An arithmetic average is widely used in statistics.  It is the most widespread type of averages. The middle arithmetic is determined as attitude of sum of separate values of sign toward the amount of units of aggregate. Distinguish middle arithmetic simple and weighed. Middle the arithmetic simple is applied then, when the individual values of avarage sign are known in every unit of aggregate. Middle arithmetic the weighed is calculated, when the separate values of average sign repeat oneself in the probed aggregate different number one times, and weighing in this case conduct after frequencies which show how many times a certain variant repeats oneself. A geometrical average is utillized for determination of middle rates of dynamics of the meaningful phenomena. A quadratic average is used at the study of connections between the probed phenomena and their reasons by the method of correlation analysis but other

     Will apply theoretical material to our project task and will expect simple averages.
