The GovStat Statistical Interactive Glossary (SIG)

摘要

The websites of U. S. statistical agencies provide statistical information on a wide range of American life, ranging from unemployment to crop prices to birth rates. Like other complex information resources, they are not always easy to use, especially for inexperienced or nonexpert users. One of the problems that people have in using statistical information is that the level of statistical knowledge (also known as statistical literacy) in the general population is low. People's lack of statistical knowledge is a barrier to many important tasks: searching for information, deciding which of several kinds of statistics they need, understanding the meaning of table, row, and column titles, understanding what a specific number means, interpreting the meaning of a time series, and so on.
