# Advice 1: How to solve problems on statistics

Statistics is a science and an academic discipline that is included in the program in various specialties. The task of statistics to solve both students and employees of various organizations to perform their business functions. Such tasks may have different goals, respectively, in various solutions. However, they share a common goal – to identify and analyze the relationship between the quantitative and qualitative party to any mass phenomena. To solve any problem according to the statistics, you need to perform a number of steps.
You will need
• MC Excel, basic formulas of statistics
Instruction
1
The first thing to sort on the selected characteristic data set that you want to perform. Then, the resulting data group to combine columns of the table. In some cases, the data needed for the solution may not be enough, then they need to be calculated using the appropriate formula in statistics or mathematical formulas.
2
Based on task, you must calculate the required pattern, using the value of the required series. In carrying out this calculation apply the basic formulas of statistics: averages, ratios, indexes, indicators. These formulas with an explanation of the legend can be found in textbooks on statistics or on the Internet.
3
As a rule, the resulting calculation is required to represent graphical images. For this program, which is working, you need to select the column and choose the desired image: graph or chart.
4
On the basis of the calculations and graphics need to analyze the obtained data, compare them to each other and thus find the answer to the problem.
The most convenient tool for the solution of problems in statistics is the MC Excel program which makes everything simpler.

The Internet is easy to find examples of solved problems on statistics which can be used as a good example.

# Advice 2: How to solve logistics challenges

Before every organization, there are a lot of logistical problems. The subject of "logistics" is introduced in the curriculum of many specialists. Problem solving – one of the best ways to reinforce material. For solving problems in logistics by using different methods, including from the other scientific fields.
You will need
• - a manual for logistics;
• - pen and paper;
• - computer table-editor.
Instruction
1
Be sure to carefully read the prerequisite tasks, write in an easy to understand view of the data that is given to you, and what you need to find. Remember how you did in math in school.
2
As a rule, for solving problems in logistics require the preparation of tables and graphs that allows us to represent the solution graphically. For convenience, you can use the table editor, and then the resulting materials to print.
3
Define a method that must be applied to solve the set tasks (often specified in the condition task). The mathematical methods include probability theory, theory of random processes, mathematical statistics, logic, the theory of matrices and others.
4
Also used methods of the theory of operations research: linear, nonlinear, dynamic programming, Queuing theory and inventory management, the theory of efficiency, simulation, etc. Apply methods of technical Cybernetics, such as the theory of prediction, theory of large systems, graph theory, scheduling, information, General control theory, etc.
5
In a textbook on logistics you can find the theoretical aspects of applying the required methods and examples of solving problems. Disassemble them and use this to obtain response to you. By the way, most problems can be solved not by one method, so you can always check the correctness of the reasoning.
6
Made on the first draft of the assignment after the check copy and complete in accordance with the requirements of the teacher. At the end of the task, be sure to select the answer.
Currently there are many software systems that solve logistical problems. For example, in the table editor MS Excel built a variety of formulas for processing of the logistics data.

# Advice 3: How to solve the problems in the economy

In the course of studying economic disciplines to solve tasks it is necessary not too often. However, to learn how to solve them it is necessary - it can be useful at workand in everyday life.
Instruction
1
Typically, in the course of studying economisch disciplines, students faced challenges in learning economic theory, micro and macroeconomics. This is, perhaps, three subjects, which along with the theory meet objectives. These tasks are mostly simple, but they have one distinctive feature: they cannot be solved without a knowledge of the theory. And the theory necessary to know not only of this section, and from the very beginning of the discipline, because in the economy everything is interconnected.
2
If, for example, in mathematics, you can begin to explore the ranks, not knowing statistics or calculus, then you absolutely can not hurt. You are wonderful will decide the ranks, and knowledge of statistics you do not need. In the economy are exactly the opposite: not mastered the basics of economic theory, you will not be able to solve the problem of microEconomics, since all the concepts are there linked. The main rule when solving problems in the economy – thoroughly learn the theory.
3
The task in the economy of frequently used graphics. To find the breakeven point, consider the indifference curves to see rising costs on the chart the easiest. So you'll also have to master the art of charting. How to build them, are described in the same theoretical part. Even if you solve the problem related to the recent economic crisis, you, whether you like it or not, will have to study economic concepts and monetarists, and of the physiocrats and the Marxists. Otherwise you will get confused in concepts and definitions.
The economy is not so formidable an abundance of formulas as, say, mathematics or physics, however, the formulas often abbreviatory that hard to remember. You'll have to improve my English: what to remember that IC is an opportunity cost, it is easier to mentally translate "imputed cost" and it will be clear what was going on. This will help in solving problems.
