  Mann-Whitney U - Wikipedia, the free encyclopedia
In statistics, the Mann-Whitney U test is a non-parametric test for assessing whether the medians between two samples of observations are the same.
The U test is useful in the same situations as the independent samples Student's t-test, and the question arises of which should be preferred.
This is an error: it tests whether the two samples come from a common distribution, and Monte Carlo methods have shown that it is capable of giving erroneously significant results in some situations where samples are drawn from distributions with the same mean and different variances.

The test found a type of radioactive gas that would be present after a nuclear detonation, the official said.
But those test results did not necessarily mean the North Korean blast was not a nuclear explosion, that official said, speaking on condition of anonymity because he was not authorized to disclose the sampling results.
The U.S., which has sought tough steps in the United Nations that could leave the door open to a blockade or other military action, has had to give ground to gain support from China and Russia.

 WINKS Statistics Software for Research - Mann-Whitney Nonparameric Comparison
The test statistic for the Mann-Whitney test is U. This value is compared to a table of critical values for U based on the sample size of each group.
If U exceeds the critical value for U at some significance level (usually 0.05) it means that there is evidence to reject the null hypothesis in favor of the alternative hypothesis.
The largest of U or U' is compared to the critical value for the purpose of the test.

 CNN.com - U.S. launches test Scud over Pacific - Nov. 25, 2002
The test was conducted to obtain flight data, and did not involve an intercept attempt, he said.
It was the military's second launch this month of a Scud, a ballistic missile that was developed by the Soviet Union in the 1960s and is now in the arsenals of at least 25 nations, including Iraq.
The Patriot was put to the test during the 1991 Gulf War, when Iraq fired about 90 Scuds.

Aguilar says the 20-year-old citizenship test the flashcard is based on is "flawed" and is in the process of a $6 million redesign.
The next test, set to be given to prospective citizens no later than January 2009, "will be based on the components of a basic civics curriculum and will be an exam that can serve as a tool to encourage civic learning and patriotism," Aguilar says.
He says the current test, unveiled in 1986 as the first standardized exam ever given to citizenship applicants, is imprecise in several areas.

The current test is heavy on historical facts and includes questions about the colors of the U.S. flag and the name of the form used to apply for citizenship.
Officials will test 125 new questions on 5,000 people and eventually narrow the group of questions to 100, the same number that can be asked on the current exam.
All U.S. citizens -- not just new ones -- could brush up on their civic knowledge, said Roger Clegg, president of the Center for Equal Opportunity, a conservative think tank that supports the assimilation of immigrants.

 MissileThreat :: Ronald Reagan Ballistic Missile Defense Test Site (RTS)
In 1954, the U.S. detonated the most powerful hydrogen bomb ever tested, known as “Bravo.” Radiation from the blast was so intense that Marshallese and U.S. military personnel had to be evacuated from the region, although all were allowed to return by 1957.
In addition to testing long-range interceptor missiles, RTS has the ability to support interceptions of Scuds and other short- and intermediate-range ballistic missiles in various tactical scenarios, thus allowing it to serve as a test site for smaller, mobile systems such as the Patriot Advanced Capability-3 (PAC-3).
The purpose of the test was to gather data on the weapon and determine whether the Mark-2 re-entry vehicle is effective on the Minuteman-3.

U.S. Secretary of State Madeleine Albright said that U.S. officials would bring up the issue Monday during ongoing talks with North Korea over its compliance with an agreement to freeze its nuclear weapons program.
U.S. State Department spokesman Lee McClenny stressed that this missile test is "a matter of deep concern to the United States because of its potentially destabilizing impact on northeast Asia and beyond."
U.S. intelligence analysts believe North Korea has enough plutonium to create at least one nuclear weapon, along with a wide variety of chemical agents and limited biological weapons.

Officials said the operation would be led by Army Gen. Tommy Franks, the chief of Central Command, and acknowledged that shifting at least some operations and personnel from Florida to Qatar on a permanent basis was under consideration.
In recent months, the number of U.S. warplanes and personnel at the base have swelled, with about 2,000 troops now populating a large military tent city in the desert, according to one official.
Franks decided to remain in Tampa, defense officials said, because he and Rumsfeld thought a move would be disruptive during the opening stages of the war and believed that Saudi Arabia would have objected to stationing the headquarters at Prince Sultan.
