Let’s calculate middle harmonious for resulting and for two factors indication:

Let’s calculate middle arithmetic for resulting and for two factors indication:

Let’s calculate middle quadratic for resulting and for two factors indication:

For checking our results we can use the rule of majorities:

For the average selling price of poultry: .

For the cost of poultry: .

For fund of meat consumption to 1 person: .

As we see the rule of majorities executing.

For the calculation of middle arithmetic by the method of moments it is necessary to use two properties of middle arithmetic:

1) if to decrease all variants on some number , the middle will diminish on this number;

2) if to decrease variants in and one times (to divide), the middle will diminish in so much times.

Middle the method of moments calculated on a formula:

,

where – is a moment of the first order. He is evened:

,

where – number which all variants diminish on, more frequent this variant, that is in a middle a row or has most frequency;

– size of interval (as in our case row of exactly interval).

Using the interval variation row of distributing at the level of average selling price of poultry, we will define the middle level of average selling price for all aggregate methods of moments. Calculations are in table 8

TABLE 8

Calculation of middle arithmetic of the average selling price of poultry

By the method of moments

Yields of wheat, 100hectare/h	Frequency,	Center of the interval, y
482,3 – 710,88		596,59	-228,58	-1	-5	2982,95
710,88 – 939,46		825,17				5776,19
939,46 – 1168,04		1053,75	228,58			3161,25
1168,04 – 1396,62		1282,33	457,16			6411,65
1396,62 – 1625,2		1510,7	685,53			7553,5
Total:		X	X	X		25885,54

Results of calculation we put in formula:

Parallel determine middle arithmetic self-weighted:

Consequently, middle arithmetic, expected two different by methods, gives a the so same result, and we can assert that middle level of average selling price of poultry will be equal to 1035,46.

Using the interval variation row of distributing at the cost of poultry, will define the middle level of the cost of poultry for all aggregate the method of moments. Calculations are in a table 9.
