Analysis and examination of data from the 2025 national civil service examination - details determine success or failure Enter reading mode

Data analysis is a very important part of the test preparation and examination. If we want to improve the accuracy of data analysis, we must pay attention to carefully examine the questions in the usual practice process. Don't neglect the material notes and details of the questions because of nervousness and saving answer time. Zhonggong Education now leads you to learn how to distinguish details.

[Example 1] At the end of 2012, the total population of mainland China was 1354.04 million, with 16.35 million births and 9.66 million deaths throughout the year. At the end of 2012, there were 222.87 million people aged 0-14 (including those under the age of 15), accounting for 16.5% of the total population; 937.27 million people of working age aged 15-59 (including those under 60), accounting for 69.2% of the total population; There are 193.9 million people aged 60 and above, accounting for 14.3% of the total population.

Question: In 2012, the number of people aged 1-14 (including those under 15) in mainland China was:

A. 206.52 million people B.239.22 million people C.222.87 million people D.163.5 million people

[Answer] A. Chinese public resolution: In this question, it should be noted that the number of people aged 0~14 is given in the material, including both 0~1 and 1~14 years old, while the question is 1~14 years old, and the statistical endpoints are different. It can be seen from the materials that in 2012, there were 222.87 million people aged 0 to 14 (including those under the age of 15), of which 16.35 million were born (including those under the age of 1), so the population aged 1 to 14 (including those under the age of 15) was 22287-1635. The last two options were different, and the last two were calculated as 87-35, and the last two were 52. Therefore, A was selected for this question.

[Example 2] From January to February 2017, 9.36 million deadweight tons of shipbuilding were completed nationwide, up 123% year on year; It undertook 2.21 million dwt of new ship orders, up 133% year on year. At the end of February, 92.07 million deadweight tons of hand held ships were ordered, down 22.6% year on year and 7.6% from the end of 2016.

From January to February 2017, 9.07 million deadweight tons of export ships were completed nationwide, up 127% year on year; Orders for export ships were 1.91 million deadweight tons, up 122% year on year. At the end of February, 84.06 million deadweight tons of hand-held export ships were ordered, down 25.9% year on year.

From January to February 2017, 53 key monitoring shipbuilding enterprises (hereinafter referred to as key enterprises) completed 9.12 million deadweight tons of shipbuilding, up 133% year on year. It undertook 1.97 million deadweight tons of new ship orders, up 119% year on year. At the end of February, 88.74 million deadweight tons of ships were ordered, down 23.1% year on year.

From January to February 2017, key enterprises completed 8.86 million deadweight tons of export ships, a year-on-year increase of 138%; It undertook 1.71 million dwt orders for export ships, up 109% year on year. At the end of February, the orders of hand-held export ships were 81.29 million deadweight tons, down 26.6% year on year.

Question: If the proportion of export ship completion in January February 2017 in the national shipbuilding completion is X, the proportion of export ship orders in the national new ship orders in the same period is Y, and the proportion of handheld export ship orders in the national handheld ship orders at the end of February is Z, then there are:

A.X>Y>Z B.X>Z>Y C.Y>X>Z D.Y>Z>X

The above are two typical questions that need attention to material details and question stem details. Zhonggong Education suggests that you can prepare a wrong question accumulation book, write topic analysis and attention points on the wrong question book, and remind yourself to pay attention to traps and question stem details in daily learning and review.
