Example questionIn 2014, China's research and experimental development (R&D) expenditure amounted to 1,331.2 billion yuan, an increase of 12.4% over the previous year, a decrease of 2.6 percentage points.

Question: 2012 China's research and experimental development (R&D) expenditure of how many billion yuan?

A.10299 B.13312 C.11843 D.12159

Trap Analysis Time Trap. The material gives the data of 2014, the question seeks the amount of 2012, the test to find the amount of every other year. Candidates often due to carelessness may calculate the amount of 2013, and thus mistakenly selected into into C. The correct answer is A. Solution:, choose the closest A option.

Tips time trap is one of the most common traps in data analysis. Candidates should be cautious attitude when encountering this topic, the answer is shown directly in the question stem should attract enough attention, not to pick up the mentality of ready-made cheap, hasty answer. For the question stem appears more than one time or percentage points of the situation, be sure to find out the question of the time, not lightly.

2. unit trap

In the data analysis questions, there will often be a number of mixed units, such as kilometers and miles, hectares and acres, ten thousand and billions of tons and kilograms,; material given in a unit, but in the question or option is another unit, which is the unit trap.

Example 2013, the national commercial property sales area of 1305.51 million square meters, an increase of 17.3% over the previous year, the growth rate of 3.5 percentage points lower than in January to November, 15.5 percentage points higher than in 2012; of which, the residential sales surface growth of 17.5%, office sales area growth of 27.9%, the sales area of commercial business premises growth of 9.1%. Commercial property sales 8142.8 billion yuan, an increase of 26.3%, the growth rate than January to November fell 4.4 percentage points, an increase of 16.3 percentage points over 2012; of which, residential sales growth of 26.6%, office building sales growth of 35.1%, commercial business housing sales growth of 18.3%.

Question: How many millions of square meters of commercial real estate sales in the country in 2011?

A.92000 B.109000 C.9.8 D.10.9

Trap Analysis Unit Trap. Material given in units of 10,000 square meters, the unit of the question is billion square meters, the correct answer is D, students if they do not look at the unit is easy to mistakenly choose B option. Solution: there is a question to know, 2012 growth rate of 17.3% - 15.5% = 1.8%, then the required: 10,000 square meters, that is, 1.09 billion square meters, only D is consistent.

Tips in the topic of units, especially about the average amount of points, the need to convert units, candidates should remember to convert between units, to avoid the calculation of the correct but the answer is the wrong choice of this situation.

3. Relative Trap

Relative refers to the ratio of two related numbers, in the data analysis is often examined in the form of a percentage, such as the proportion of the growth rate.

Example questions 2016 Jiangsu Provincial Exam questions a city statistics bureau in a survey against noise nuisance, when asked which type of noise respondents resent, the choice of community square dance activity noise accounted for 8.6%, 2.9 percentage points lower than the choice of residential community pet dog barking. When asked if they support square dance activities, 12.8% of the citizens surveyed said they did not care or did not know, 12.0% of the respondents said they were against it, and the rest were supporters. Among the supportive citizens, when asked about the main reason for their support (multiple choice), the responses of respondents of different age groups are shown in the chart below.

Question: 100.The following judgment is correct ( )

A.16.3% of the middle-aged respondents in this survey think that activities such as square dancing can be overcome through standardized management

B.The proportion of young people is higher than that of the middle-aged and the elderly in this survey

Trap Analysis Relative Number Trap. This question should be part of the students will mistakenly choose A, and will blindly think that it must be right, this is not a table directly given in the data, very relieved to choose A, the other do not look at it. The correct answer to this question is option D. For D, you should not be difficult to understand, not to repeat. Let's see where A is wrong? Let's read the title of the table: "support for square dancing and other activities of the responding citizens to choose the proportion of each main reason", A option is asked in this survey of 16.3%, so the relative number of 16.3% of the relative number of the corresponding whole is different, a total number of people surveyed, one of the number of people surveyed to support square dancing and other activities, so A is not correct.

Tips in the topic of the proportion and other relative numbers, be sure to distinguish between the numerator and denominator of the relative number, which amount is relative to which amount, do not be careless correct option, wrong choice of other options.
