You first need to understand why the usual method, the average valuation

**of the product**is not suitable for use. Price list of any company involved in the trade, usually several hundred SKUs. It rarely happens that they are the**product**of the mi-substitutes, competing with each other. This range is ineffective and generally leads to a contraction of demand, rather than expansion and revenue growth. So usually every company tries to occupy a niche in different product groups. It is obvious that to calculate the average**cost**of goods by dividing the total price by the number of positions is impossible. The resulting number will reflect "the average temperature in the hospital".2

Therefore, the more accurate is the calculation of the average arithmetic weighed. It is produced in two stages. To calculate average

**cost****of goods**, break the range into groups of homogeneous goods can be compared by price. Within each group determine the average**cost**of conventional products division of price by quantity. Next, find the proportion of each group in total production volume.3

Then, to calculate average

**cost**of goods, multiply the percentage of each group in the total number of products at the appropriate average prices. Thus obtained, the final price will be much more accurately reflect the average**cost****of the goods**. However, even this option may not be suitable, if products is too heterogeneous, for example, food products and industrial goods. In this case it is more correct to calculate average**cost****of goods**for each product.# Advice 2: How to determine the average number

All the known numbers can be mentally laid out in a line, this line is called

**numerical**axis. It is located at the ascending of the mathematical values from minus infinity to plus infinity. And if you choose any two points, it is possible to determine by calculation how many will be between them, that is, to determine their**average**number.Instruction

First, it follows from these two numbers determine the minimum and maximum comparison. Then from the larger value to take less. Example. You need to determine

**the average**value between the numbers 14 and 76. Seventy-six more than fourteen. The difference between these numbers: 76-14=62, is sixty two.2

If is

**the average**value between numbers with different modules (positive and negative), then the difference should be found by the rule of subtracting numbers with different signs: from the larger number to take less and put the answer the sign of the larger number. Example: the difference between the numbers -3 and 6 to find how |6-3|=3 and assign the answer to a plus sign.3

Then, the obtained difference is divided by the number of integers among which the need to find

**the average**value. Defined in the above example**, the average**value is between two numbers, then finding the average value should be found to split the difference, equal to sixty-two by two. It turns out, 62/2=31. Answer:**the average**between the numbers fourteen and sixty-two is the number thirty-one. It is located on the**numeric**axis exactly between these values.# Advice 3: How to calculate the average number

From the point of view of mathematics the average

**number**may be**higher**exponential, quadratic, harmonic, weighted, logarithmic, etc. However, in practice, the average person often have to calculate simple arithmetic average value of some set of values. In General, this**average**number can be defined as a number between the largest and smallest numbers of the given sequence.Instruction

Put all the numbers of the original sequence, and then divide them by the total number of numbers to get

**the average**arithmetic value. If the task has an applied character, the result may need rounding to get the answer in the form of "half digger".2

If such a computation is ad-hoc, and the numbers in the source sequence is not much, for the practical calculation of the values you can use the calculator built into Google search or Nigma. Specify and enter the required mathematical operation in the search query box of the system. For example, if you need to find

**the average**number of goals conceded by CSKA in their last five games, enter the query: "(0+1+2+1+1)/5". The search result will show without you click send request.3

If the sequence numbers are not so small, it is better to use the tabular editor such as Microsoft Office Excel. Editor, you will be given a table to fill in values for the original sequence of numbers. This can be done entering the numbers manually, but if it is possible to copy and paste the numeric sequence in the text format, it will be much easier. In this case, preferably by using any text editor before copying replace all delimiters between values of a sequence to characters of a string - then after pasting into Excel, the values will line up in the column. If instead of end-of-string use the tab character, they will line up in a row.

Select the column (or row) that contains the entered values by clicking on its header. The arithmetic mean can be seen in the table below in the status bar.

5

If you only know this value is not enough, then use the formula to calculate the average. To do this, click the cell where you want to see the result, open the drop-down list on the button with the pictogramme the Greek letter Sigma Σ in the section "Edit". Select the list item 'Average', and then select the filled range of table cells and press Enter. Excel will calculate and display

**the average**value.# Advice 4: How to determine the average unit weight

Every science that can be called accurate primarily collects research data through observation, sampling, experiments and surveys. The huge flow of information in the process of hard work is processed to obtain average data. They are calculated and then used in physics, mathematics, statistics, and other Sciences.

Join in the preparations for the calculations. Collect as much information needed to obtain a finite number. The more and better the information, the more accurate will be the final figure. For example, you need to determine the average specific weight of wages in cost of production in the factories of a certain category (say, canning) in our country. You will not be able to know for certain the exact number of such plants, a lot of them, but nevertheless it is necessary to collect data. So make the maximum possible list of them, and for each find out the total amount of wages and the total cost.

2

Information take for a certain period of time: per month, per quarter, per year. Note that you can give you can only when the period is already closed in financial accounting. Current information you can not give because of their constant change. So choose only the last time, but still not very long ago that information was outdated.

3

Such large-scale work no longer, if you need the average unit weight for the three identified plants. In this case, you just narrow the scope of the study, taking the figures only of these companies.

4

If specific figures are not available, calculate them yourself based on the amount that you will be able to give the company. Remember that when processing the data one amount always flows logically from certain others and Vice versa. So, you can give the salaries of the workers in the shops – and you only summarize. Or, on the contrary, will report the total amount of wages, but it will add staffing, which shows the specialty of the employee, and the estimated salary statement. Then, by sampling only looking for workers.

5

Summarize all the numbers that managed to get. At the exit you will have two figures. In this example, the total salaries of all the workers in the factories and the total cost of canned products.

6

A great deal of preparatory work has been done, so now it remains to perform a simple arithmetic operation: the sum divided by the second and multiply by a hundred. In numbers it looks clearer, so we turn again to our case. If the amount of wages was 120, and the cost of production – 400 (arbitrary numbers), the average share of wages in the cost of canned products in the country will be 30%.

120/400*100=30.

120/400*100=30.

7

If you spend this is simple enough even and for each enterprise individually, you will be able to compare how the percentage share of each plant will differ from the average in one direction or another
