There are usually five special items in the examination content, among which the science part is quantitative relationship and data analysis. Quantitative relationship is a relatively rare topic for some candidates, and data analysis is just the opposite. As long as you review for a period of time, the correct rate will often improve quickly. In other words, for the special subject of data analysis, the input-output ratio of candidates is relatively high, which is often part of our high score, especially for preparing for the 20 17 singing civil service exam. We will achieve obvious learning results in special exercises. In view of its importance, the teacher who came to China to teach graphics will take us into data analysis and unveil its mystery.

As we all know, it is a very important link to read the stem information and make clear what the stem seeks when doing the purpose of the question. Because every topic, we can find out what this question is asking by reading the stem, and the question is often the starting point of our thinking, and then we can solve it by thinking about it. Finally, we can answer this question and go back to the stem itself, which is the end of our thinking. It can be seen that reading the stem information is the first step for us to answer the questions correctly. So what problems have appeared in the real questions of data analysis over the years? According to the summary of practical problems in the past five years, painting education can be divided into five categories:

The first category: short answer questions.

This kind of questions appear frequently in data analysis, which belongs to a kind of hot questions in the exam, mainly referring to a kind of questions that can be answered directly by using familiar formulas. When doing this kind of problem, we need to pay attention to whether the time required by the problem is consistent with the time given by the material, then review the formula according to the test center, and finally find the relevant data in the material according to the formula, list the formula of this problem and answer it.

For example, the material information shows that in 20 14 years, there were129.25 million newly registered market entities nationwide, an increase of1609,700 households, including 3.65100000 households, 8.9645 million individual industrial and commercial households and 309,500 farmers' professional cooperatives.

Question: In 20 14 years, the proportion of individual industrial and commercial households in the newly registered market in China is about:

This question is simple. First of all, it depends on whether the time required by the question (20 14) and the time given by the material (20 14) are consistent and obviously consistent, that is, to find the current period, you can directly use the numbers in the material; Then, analyze the test sites of this question and investigate the proportion. In the formula, the current proportion = part/whole; Finally, according to the formula, some and all corresponding data are found in the material, and the formula is listed as 896.45/ 1292.5, so the formula can be estimated.

The second category: multi-test site combination.

This kind of topic is of moderate difficulty, and it is easy to score after simple review, mainly because the description of the stem will involve multiple test sites and multiple formulas. When answering such questions, the requirements for candidates will be higher, mainly because they need to find all the test sites involved in the questions and write relevant formulas.

Example: According to the material information, in 20 14 years, the investment in office building development nationwide was 465.2 billion yuan, up by 38.2%, and the investment in business building development was1194.5 billion yuan, up by 28.3%.

Question: In 20 14 years, how many times did the investment in office development in China increase compared with that in commercial buildings?

The stem of this question mentions two test sites: the sum of growth and how many times. As long as we can write the formula of how many times the sum of growth is, this problem will be solved easily. Growth = current/1+ growth rate, that is, several times = number 1÷ number 2, then the growth required for this problem is 1=4652÷( 1+38.2%), and the growth is 2 =/kloc-.

The third category: the problem of determining the premise.

The first step is the key when doing this kind of problem. If the first step is wrong, there will be no solution later. Therefore, determining the correct premise is the key to solve this kind of problem.

Material information: Table 20141-May: Software business income of software and information technology services in sub-provincial cities.

Question: During the period of 2014-1-May, the income of information technology consulting services in the sub-provincial cities with the fastest year-on-year growth rate is about several times that of the sub-provincial cities with the slowest growth rate.

The fourth category: the clever use of process quantity.

This kind of question is difficult to answer, and some candidates are prone to make mistakes. When doing this kind of questions, we should carefully read what is the connection between the known information given in the materials and the information needed for the stem of the questions. There is often no direct connection, but it can be answered by an intermediate quantity.

According to the data, the financial industry accounts for 34.5% of the tertiary industry and 28.4% of GDP.

Question: What is the proportion of tertiary industry in GDP?

This topic is very simple. Just find the corresponding value of the tertiary industry and GDP, and you can answer it. However, the data is not given directly in the material information, but is given by the relevant data of the financial industry. Then we can use the data of the financial industry to express these two requirements respectively, and then simplify them, and finally list them as 28.4%÷34.5%, and estimate this formula.

The fifth category: information search questions.

This kind of topic is the simplest one, which belongs to the topic of direct scoring. No calculation is needed. You only need to understand the meaning of the stem itself, and then you can find the relevant information directly in the material to answer. There are about 2 questions every year, which are very popular with all our candidates and are generally not difficult.

Tuhua Education believes that if you really want to get high or even full marks in this part of data analysis, you still need to work harder, especially when the exam is approaching. This topic is the key part of our review. As long as you can grasp the score of this place and get the overall score, you can go up a storey still higher.
