The cumulative value of GDP is -100 million yuan" "The cumulative year-on-year growth rate of GDP is -%."

You can just make it up yourself, this thing is all made up. There is no difference between you and someone else.

Select b Variance.

Extended material: Basic concepts of variance.

Variance is the mean of the sum of the squares of the deviations of individual data from their arithmetic mean, usually expressed as 2. The unit of measurement and dimension of variance are not convenient to explain in an economic sense, so the arithmetic square root of variance-standard deviation is used to measure the degree of difference in statistical data. Variance and standard deviation are the most important and commonly used measures of the degree of variability in data.

Standard deviation is also known as mean square deviation and is generally expressed by . Variance and standard deviation are also calculated by simple mean and weighted average, and the formulas are slightly different for population and sample data. The variance is the mean of the squares of the difference between individual data and the mean.

Mode. The mode is the median value of the group with the highest frequency of the sample observations in the frequency distribution table, which is mainly used in large-area census research.

The mode is the data that occurs the most times in a set of data, and is the original data in a set of data, not the corresponding times.

There is more than one mode in a set of data, such as in the data , both appear twice, and they are both modes in this set of data.

Generally speaking, the number with the most occurrences in a set of data is called the mode of this set of data.

For example, the mode of 1,2,3,3,4 is 3.

However, if two or more numbers occur the most often, then those numbers are the mode of the data.

For example, the mode of 1, 2, 2, 3, 3, 4 is 2 and 3.

Also, if all data occurs the same number of times, then there is no mode for that set of data.

For example, 1, 2, 3, 4, 5 do not have a mode.

In a Gaussian distribution, the mode is at the peak.

Representing a set of data using the mode is less reliable, but the mode is not affected by extreme data and is easy to find. In a set of data, if there is a large change in individual data, it is appropriate to choose the median to indicate the "central trend" of the data.

This is particularly useful when there is no clear order in the numerical values or the observed person (often in non-numerical data), as the arithmetic mean and median may not be well defined.

Example: The mode of is a fish.

Mode calculation is the most commonly used and most represented in sales.

Since variance is a measure of the amount of fluctuation in a set of data, "fairly flat between growth rates" refers to the variance of the data

Therefore, choose B

In the second quarter of 2009, China's economy stopped falling and rebounded. According to the data released by the National Bureau of Statistics, from the perspective of GDP operation trend, according to the performance and trend analysis of the main economic indicators in the two months of 2009, the second quarter showed a more obvious trend of stopping the decline and rebounding.

In the first quarter of 2009, China's economy well, 4 days to look back to the second construction.

Let's see what others have to say.

The National Bureau of Statistics** has specific data, which is more accurate through your own calculations.

Xinhuanet, Beijing, January 21 (Reporter Liu Zheng, Zhou Yingfeng) The data released by the National Bureau of Statistics on the 21st shows that China's GDP in 2009 was 335353 billion yuan, an increase of 8 7 over the previous year on a comparable basis.

Ma Jiantang, director of the National Bureau of Statistics, said at a press conference held by the National Information Office that in the face of the serious impact of the international financial crisis that has not been encountered in a century and the extremely complex domestic and foreign situation, the National Bureau of Statistics has judged the situation and made scientific decisions, led the people of the whole country to work together to overcome the difficulties, adhered to the implementation of a proactive fiscal policy and a moderately loose monetary policy, comprehensively implemented and continuously improved the package of plans to deal with the international financial crisis, and quickly reversed the situation of a significant decline in economic growth. The overall rebound of the national economy has been realized.

In terms of quarters, China's economy grew by 6 2 in the first quarter of 2009, 7 9 in the second quarter, 9 1 in the third quarter, and 10 7 in the fourth quarter.

Statistics show that in 2009, China's agricultural production continued to develop steadily, and industrial production rebounded quarter by quarter. The total annual grain output reached 530.82 million tons, an increase of 0.4 compared with the previous year, and the output increased for six consecutive years; The added value of industrial enterprises above designated size increased by 11 0 over the previous year, and the added value of the industrial enterprises above designated size increased by 18 0 in the fourth quarter.

Investment continued to grow rapidly, and market sales grew steadily. In 2009, China's investment in fixed assets was 224846 billion yuan, an increase of 30.1 over the previous year, and the growth rate was 4.6 percentage points faster than that of the previous year. The total retail sales of consumer goods for the whole year 125343 billion yuan, an increase of 15 5 over the previous year, and the actual growth rate was 16 9 after deducting the first factor, and the actual growth rate was 2 1 percentage points faster than the same period last year.

Household consumption** and industrial product ex-factory sales** declined throughout the year and rose at the end of the year. In 2009, China's household consumption** decreased by 0 7 over the previous year, and in December it increased by 1 9 compared with the same period last year; The annual ex-factory sales of industrial products fell by 5 4 and 1 7 in December.

The income of urban and rural residents has grown steadily, and the employment situation is better than expected. In 2009, the per capita disposable income of urban residents in China was 17,175 yuan, a real increase of 9 8 after deducting the first factor; The per capita net income of rural residents was 5,153 yuan, an increase of 8.5 yuan in real terms. For the whole year, there was a net increase of 9.1 million in urban employment over the previous year.

Answer B Analysis: Based on the significance analysis of median, mode, mean, and variance, only variance reflects the magnitude of fluctuations in a set of data

Answer: Since variance is a measure of the amount of fluctuation in a set of data, "fairly flat between growth rates" refers to the variance of the data

Therefore, choose b Comment: The significance of variance in this question is used to measure the amount of fluctuation in a set of data, the larger the variance, the greater the deviation from the mean of this group of data, that is, the greater the fluctuation, the more unstable the data; On the contrary, the smaller the variance, the more concentrated the distribution of this group of data, and the smaller the deviation of each data from the mean, that is, the smaller the fluctuation and the more stable the data

No... China is developing, and the United States is like a flower to thank you, and we in China are just blooming seedlings.

In the first three quarters of 2010, China's GDP at current prices was preliminarily estimated at 100 million yuan (US$100 million), a year-on-year real increase.

According to data released by the National Bureau of Statistics of China at 10 a.m. on October 21, preliminary estimates show that the GDP in the first three quarters was 100 million yuan, calculated on a comparable basis, a year-on-year increase, and an increase of one percentage point over the same period last year. In terms of quarters, the first quarter of growth, the second quarter of growth, and the third quarter of growth.
