sign

Examples of sign in the following topics:

• Symbols and Nature

  • Semiotics is the study of signs.
  • A sign is a symbol that stands for something else.
  • In French, the sign for the same object is "voiture".
  • Language is traditionally thought to consist of three parts: signs, meanings, and a code connecting signs with their meanings.
  • Signs can consist of sounds, gestures, letters, or symbols, depending on whether the language is spoken, signed, or written.

• Statistical Literacy

  • This webpage gives the FBI list of warning signs for school shooters: http://news.bbc.co.uk/2/hi/americas/1205252.stm.
  • Do you think it is likely that someone showing a majority of these signs would actually shoot people in school?
  • The warning signs are unlikely to be sufficiently predictive to warrant the conclusion that a student will become a shooter.
  • If an action is taken on the basis of these warning signs, it is likely that the student involved would never have become a shooter even without the action.

• Sign Test

  • The sign test can be used to test the hypothesis that there is "no difference in medians" between the continuous distributions of two random variables.
  • One such statistical method is known as the sign test.
  • As outlined above, the sign test is a non-parametric test which makes very few assumptions about the nature of the distributions under examination.
  • The test statistic $x$ is then the number of plus signs.
  • The sign test involves denoting values above the median of a continuous population with a plus sign and the ones falling below the median with a minus sign in order to test the hypothesis that there is no difference in medians.

• The Rule of Signs

  • We can see that the negative signs cancel out for any even power.
  • This function has one sign change between the second and third terms.
  • We know that the number of roots of either sign is the number of sign changes, or a multiple of two less than that.
  • To find the positive roots we count the sign changes.
  • Since there are no sign changes, there are no positive roots $(p=0)$.

• Higher Education

  • It was signed into law on April 11, 1965, less than three months after it was introduced.
  • The Higher Education Facilities Act of 1963, which was signed into law by Johnson a month after he became president, authorized a dramatic increase in college aid within a five-year period and provided better college libraries, 10-20 new graduate centers, several new technical institutes, classrooms for several hundred thousand students, and 25-30 new community colleges each year.
  • This major piece of legislation was followed by the Higher Education Act of 1965, signed into United States law on November 8, 1965 at Texas State University.
  • This signing plaque rests on campus grounds of Texas State University commemorating the Higher Education Act.

• Introduction to Blood Pressure

  • Blood pressure is a vital sign reflecting the pressure exerted on blood vessels when blood is forced out of the heart during contraction.
  • Blood pressure is one of the principal vital signs.
  • Blood pressure and pulse, or the vital signs, are measured as indicators of several aspects of cardiovascular health.

• Language

  • Another definition sees language as a formal system of signs governed by grammatical rules of combination to communicate meaning.
  • This definition stresses the fact that human languages can be described as closed structural systems consisting of rules that relate particular signs to particular meanings.
  • When described as a system of symbolic communication, language is traditionally seen as consisting of three parts: signs, meanings, and a code connecting signs with their meanings.
  • The study of how signs and meanings are combined, used, and interpreted is called semiotics.
  • Here, a bilingual sign in Wales tells both English and Welsh speakers that smoking is prohibited.

• The sun rise of your new business and accessing market opportunity: the initial rim of the wheel

  • Recognizing when you are on the verge of going through a Stop Sign without braking is critical.
  • Blog Back: Analyze your new venture's market opportunity; do you have all "Go" signs?
  • If you have all or some "Stop" signs what can you do to remove the roadblocks that are causing your "Stop" signs?

• Cofactors, Minors, and Further Determinants

  • The cofactor of an entry $(i,j)$ of a matrix $A$ is the signed minor of that matrix.
  • Specifically the cofactor of the $(i,j)$ entry of a matrix, also known as the $(i,j)$ cofactor of that matrix, is the signed minor of that entry.
  • To know what the signed minor is, we need to know what the minor of a matrix is.
  • The determinant of any matrix can be found using its signed minors.
  • The determinant is the sum of the signed minors of any row or column of the matrix scaled by the elements in that row or column.

• Levels of measurement: Binary, signed, and valued graphs

  • This kind of data is called "signed" data.
  • The graph with signed data uses a + on the arrow to indicate a positive choice, a - to indicate a negative choice, and no arrow to indicate neutral or indifferent.
