Valid Appeal

	Valid Appeal Validity or Valid may refer to: Science/mathematics/statistics: * Validity (logic), a property of a logical argument * Scientific: Internal validity, the validity of causal inferences within scientific studies, usually based on experiments External validity, the validity of generalized causal inferences in scientific studies, usually based on experiments Valid name (zoology), in animal taxonomy Validly published name, in plant taxonomy * Validity (statistics), the application of the principles of statistics to arrive at valid conclusions Statistical conclusion validity, establishes the existence and strength of the co-variation between the cause and effect variables Test validity, validity in educational and psychological testing Face validity, the property of a test intended to measure something * Construct validity, refers to whether a scale measures or correlates with the theorized psychological construct it measures * Content validity, the ...

picture info	Validity (logic) In logic, specifically in deductive reasoning, an argument is valid if and only if it takes a form that makes it impossible for the premises to be true and the conclusion nevertheless to be false. It is not required for a valid argument to have premises that are actually true, but to have premises that, if they were true, would guarantee the truth of the argument's conclusion. Valid arguments must be clearly expressed by means of sentences called well-formed formulas (also called ''wffs'' or simply ''formulas''). The validity of an argument can be tested, proved or disproved, and depends on its logical form. Arguments In logic, an argument is a set of statements expressing the ''premises'' (whatever consists of empirical evidences and axiomatic truths) and an ''evidence-based conclusion.'' An argument is ''valid'' if and only if it would be contradictory for the conclusion to be false if all of the premises are true. Validity doesn't require the truth of the premises, inst ...

	Concurrent Validity Concurrent validity is a type of evidence that can be gathered to defend the use of a test for predicting other outcomes. It is a parameter used in sociology, psychology, and other Psychometrics, psychometric or behavioral sciences. Concurrent validity is demonstrated when a test correlates well with a measure that has previously been Validity (statistics), validated. The two measures may be for the same construct, but more often used for different, but presumably related, constructs. The two measures in the study are taken at the same time. This is in contrast to predictive validity, where one measure occurs earlier and is meant to predict some later measure.McIntire, S.A. and Miller, L.A., Foundations of Psychological Testing,2nd Edition, Sage Publishing Co., 2005. In both cases, the (concurrent) predictive power of the test is analyzed using a simple correlation or linear regression. Alignment with classical conceptions of validity Concurrent validity and predictive validity ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
	GLITS Graham's Line Identification Tone System (GLITS) is a test signal for stereo systems devised by BBC TV Sound Supervisor and Fellow of thIPSGraham Haines in the mid 1980s. It comprises a 1 kHz tone at 0 dBu (- 18 dBFS) on both channels, with interruptions which identify the channels. The left channel is interrupted once for 250 ms every 4 seconds. 250 ms later the right channel has two interruptions of 250 ms spaced by 250 ms. This arrangement has an advantage over the EBU stereo ident tone in that each channel is explicitly identified as belonging to a stereo pair. The EBU Technical DocumenMultichannel Audio Line-up Tone(Tech 3304) defines stereo lineup tone as having an interruption in the left channel only, lasting 250 ms every 3 s. Multichannel GLITS There is now an official EBU standard for a multichannel BLITS 5.1 channel ident tone which is also described in the Tech 3304 paper, along with an alternative film-style m ...
