Facing this kind of problem ： First, let's talk about basic statistical terms , Then introduce how to read the questions , If you encounter this problem again, you will be able to solve it easily .

Basic statistical terms

1. Base period quantity and current period quantity

The period for comparison is called base period , Relative to the base period is called Current period . When describing specific values, we call them Base period quantity and Current volume .

example ：2017 year Than 2016 The tertiary industry in GDP growth 6.8％,2016 Is the base period ,2017 For the current period .

2. Growth

Growth volume refers to the growth of base period volume and current period volume （ Or reduce ） The absolute quantity of .

Growth is a specific value , There are units .

Growth = Current volume — Base period quantity

The growth is positive or negative , A negative value represents the reduction .

3. growth rate

The growth rate refers to the relative change between the growth amount and the base period amount , That is, how much has it increased on the basis of the base period .

Growth rate is also called growth rate 、 growth 、 Growth rate 、 Growth rate, etc .

growth rate = Growth / Base period quantity = （ Current volume - Base period quantity ）/ Base period quantity = Current volume / Base period quantity - 1​

The growth rate is generally expressed in r The letters stand for （rate Abbreviation ）

“ Reduction rate “ The essence is a kind of ” growth rate “

4. Average annual growth

Average annual growth = （ Current volume - Base period quantity ）/ Interval year ​

5. Average annual growth rate

Current volume = Base period quantity x (1+ Average annual growth rate )ⁿ, among n Is the year of difference

6. Year on year and month on month

• Year on year ： Compared with the historical period ,2021 year 6 Month to month 2020 year 6 month ,2021 Compared with the second quarter of 2020 Second quarter
• Chain ratio ： Now the statistical period is compared with the previous statistical period ,2021 year 6 Month to month 2021 year 5 month ,2021 Compared with the second quarter of 2021 First quarter

7. The proportion of

It refers to the percentage of a certain part in the total , It's usually in the form of percentage . The proportion of = part / whole

8. Multiple

A yes B Of A/B times

9. The average

The average ＝ total / Total number of copies

10. percentage

Percentage points ： A unit of percentage

11. In numbers 、 Double

• In numbers ： Our traditional arithmetic ,” become “ Express ” One-tenth “, A few percent is equivalent to a few tenths ;
• Double ： Double to the original 2 times , double n Fan is the original 2ⁿ times

12. surplus 、 Deficit

• surplus ： At a time , A country （ region ） The amount of exports is greater than that of imports , It is called foreign trade surplus （ Also known as net exports 、 Oversupply ）;
• Deficit ： At a time , A country （ region ） The amount of exports is less than that of imports , It is called foreign trade deficit （ Also known as net imports 、 In excess ）.

Reading method ：

Graphic materials —— title 、 The horizontal axis 、 The vertical axis 、 legend 、 Company

Key reading points ： title 、 The horizontal axis 、 The vertical axis 、 legend 、 Company ;

title ： concise 、 Explain exactly the contents of the diagram , Indicate the time if necessary 、 place 、 Describe objects, etc . It is usually placed at the bottom of the figure ( Or above );

legend ： The legend is used to indicate the content represented by various symbols and colors , The legend must be consistent and complete with the graphic material , It is usually placed at the bottom or right of the figure .

Form material —— Abscissa 、 Ordinate 、 title 、 Company

Key reading points ： title 、 A banner 、 Longitudinal heading 、 Company ;

title ： The title is a summary of the main idea of the whole table material , Outline the central content of the statistical table ;

A banner ： A horizontal heading usually refers to something that is studied and analyzed , It is generally listed on the left side of the statistical table , It is equivalent to the subject of the statistical table ;

Longitudinal heading ： A data or index used to describe and analyze things , Generally listed in the upper row of the table , It is equivalent to the predicate of the statistical table ;

Company ： Appear in a heading or vertical heading , The unit of each indicator of the vertical heading .

title ：

1.2017 Third quarter of 2007 , The national average unit price per ton of imported drugs is about US $million ?

A. 2 B. 19 C. 8 D. 96

analysis ： Observation map 1 The vertical coordinate of is 10000 tons , The vertical coordinate of Figure 2 is billion dollars

2017 Third quarter of 2007 , This is the picture 2 Of 10 month 、11 month 、12 The sum of the moon divided by the figure 1 Of 10 month 、11 month 、12 Sum of the moon .

（18.4+24+27.8）/（1+1.4+1.3）=70.2/3.7=19, So the answer to this question is B term .

2.2017 In the second half of , There are several months when the year-on-year growth rate of the number of imported drugs in China is lower than that of last month ?

A. 2 B. 3 C. 4 D. 5

analysis ： From the figure 1 You know ,2017 In the second half of , The year-on-year growth rate of the number of imported drugs nationwide was lower than that of the previous month 4 individual , Respectively 7 month 、9 month 、10 month 、12 month .

3.2016 year 5 month , Month on month growth of the amount of imported drugs nationwide ：

A. exceed 100%

B. stay 40%~100% Between

C. stay 0%~40% Between

D. lower than 0%

analysis ： According to the chart data ：2017 year 4、5 The amount of imported drugs in the whole country in January was respectively 18.8 Billion dollars 、27.8 Billion dollars , The year-on-year growth rates are respectively 12.2％、54.5％. You can calculate that

2016 year 4 The amount of imported drugs in China in January ：18.8/（1+12.2％）≈16.8

2016 year 5 The amount of imported drugs in China in January ：27.8/（1+54.5％）≈18

be 2016 year 5 month , Month on month growth of the amount of imported drugs nationwide ：（18-16.8）/16.8=0.07=7％, So choose C

4. What can be inferred from the above information is :

A. 2016 In the second half of , The number of imported drugs in China is lower than 1 The month of ten thousand tons is only 2 individual

B. 2017 year 11 month , The national average unit price per ton of imported drugs is lower than that of the same period last year

C. 2017 Second quarter , The amount of imported drugs in the country exceeds 75 Billion dollars

D. 2017 year 1 month , The amount of imported drugs in the country exceeds 20 Billion dollars

analysis ：

A Options ：

According to the chart data ：2016 In the second half of the year, the quantity of imported drugs in China was ：

7 month ：1.1/（1+1％）＞1 Ten thousand tons of , dissatisfaction

8 month ：1.2/（1+13.3％）＞1 Ten thousand tons of , dissatisfaction

9 month ：1.1/（1+8.2％）＞1 Ten thousand tons of , dissatisfaction

10 month ：1/（1+7％）＜1 Ten thousand tons of , Satisfy

11 month ：1.4/（1+21.5％）＞1 Ten thousand tons of , dissatisfaction

12 month ：1.3/（1-3％）＞1 Ten thousand tons of , dissatisfaction .

Sum up , The number of imported drugs in China is lower than 1 The month of ten thousand tons amounts to 1 individual ,A error

B Options ：

According to the chart data ：2017 year 11 Monthly average unit price per ton of imported drugs ：24/1.4=17

Here because 11.9％ Less than 21.5％, That is, you can launch 2017 year 11 month , The national average unit price per ton of imported drugs is lower than that of the same period last year ,B correct

C Options ：

According to the chart data ,2017 Second quarter , The amount of imported drugs nationwide =18.8+27.8+26.5=73.1,C error

D Options ：

According to the chart data ,2018 year 1 The amount of imported drugs in the whole country in January was 22.2 Billion dollars , The year-on-year growth rate is 16.3％, be 2017 year 1 The amount of the month =22.2/（1+16.3％）=19,D error
