What do statisticians do?

经常看到有人问学统计完了以后能干吗。我觉得基本上就是两条路: academics or industry. 其实不管什么学科 基本上都是这两条路。

今天在网上乱晃悠, 无意中看到了以下。。。和大家分享一下。


What Do Statisticians Do?
The world is becoming quantitative. More and more professions, from the everyday to the exotic, depend on data and numerical reasoning.
Data are not just numbers, but numbers that carry information about a specific setting and need to be interpreted in that setting. With the growth in the use of data comes a growing demand for the services of statisticians, who are experts in the following:

• Producing trustworthy data
• Analyzing data to make their meaning clear
• Drawing practical conclusions from data

Examples of Statistics Careers
Medicine The search for improved medical treatments rests on careful experiments that compare promising new treatments with the current state of the art. Statisticians work with medical teams to design experiments and analyze the complex data they produce.
Environment
Studies of the environment require data on the abundance and location of plants and animals, on the spread of pollution from its sources, and on the possible effects of changes in human activities. The data are often incomplete or uncertain, but statisticians can help uncover their meaning.
Industry
The future of many industries and their employees depends on improvement in the quality of goods and services and the efficiency with which they are produced and delivered. Improvement should be based on data, rather than guesswork. More companies are installing elaborate systems to collect and act on data to better serve their customers.
Government Surveys
How many people are unemployed this month? What do we export to China, and what do we import? Are rates of violent crime increasing or decreasing? The government wants data on issues such as these to guide policy, and government statistics agencies provide them by surveys of households and businesses.
Market Research
Are consumer tastes in television programs changing? What are promising locations for a new retail outlet? Market researchers use both government data and their own surveys to answer questions such as these. Statisticians design the elaborate surveys that gather data for both public and private use.


What Industries Employ Statisticians?
Statistics provides the reasoning and methods for producing and understanding data. Statisticians are specialists, but statistics demands they be generalists, too. One advantage of working in statistics is that you can combine your interest with almost any other field in science, technology, or business.

Thanks, very useful

恩，很有用~谢谢~
之前自己查过wikipedia，也提到这些内容。
我还想具体工作是怎么样的？把数据输入，然后用软件处理，发现软件不够用再自己建模、编程吗？

基本上这样。。。
有的时候需要考虑数据有无缺失 能否代表整个SAMPLE  数据是否BIAS 等。。。 有的时候需要对数据做一些transformation 其实还是蛮有意思的。。。

数据很可能需要先行处理才能分析
现成的软件也许并不适合分析你手头上的数据
how to collect data is important
Also you may need to build up a model before collecting data

除此之外，Statisticians 的工作还有很多，例如
design and analysis of experiements, e.g. Boeing
sampling and survey, e.g. US Census
evironmental statisticis, e.g. EPA
cilinical trial
buiding recommender system : P e.g. Amazon, Netfilx Prize, AT&T Research
etc.

In my opinion, Statistics is about what to do in the face of uncertainty.
