GATE results are usually declared about one month after the examinations are over. The results show the total marks scored by a candidate, the GATE score, the all-India rank (AIR) and the cut off marks for various categories in the candidate's paper. The score is valid for 3 years from the date of announcement of the GATE results.
A typical predictive validity for an employment test might obtain a correlation in the neighborhood of r = .35. Higher values are occasionally seen and lower values are very common. Nonetheless, the utility (that is the benefit obtained by making decisions using the test) provided by a test with a correlation of .35 can be quite substantial ...
The motivation to test differences between samples is that ranks are in some sense maximally invariant to monotone transformations. This may be important when there is outliers or when dealing with ordinal data .
A special case of this result appeared first in 1963 in a paper by Elmer G. Gilbert, [1] and was later expanded to the current PBH test with contributions by Vasile M. Popov in 1966, [3] [4] Vitold Belevitch in 1968, [5] and Malo Hautus in 1969, [5] who emphasized its applicability in proving results for linear time-invariant systems.
A test score is a piece of information, usually a number, that conveys the performance of an examinee on a test. One formal definition is that it is "a summary of the evidence contained in an examinee's responses to the items of a test that are related to the construct or constructs being measured."
The positive predictive value (PPV), or precision, is defined as = + = where a "true positive" is the event that the test makes a positive prediction, and the subject has a positive result under the gold standard, and a "false positive" is the event that the test makes a positive prediction, and the subject has a negative result under the gold standard.
Physics Wallah Limited (commonly known as Physics Wallah; or simply PW) is an Indian multinational educational technology company headquartered in Noida, Uttar Pradesh.The company was founded by Alakh Pandey in 2016 as a YouTube channel aimed at teaching the physics curriculum for the Joint Entrance Examinations (JEE).
This rank-based procedure has been recommended as being robust to non-normal errors, resistant to outliers, and highly efficient for many distributions. It may result in a known statistic (e.g., in the two independent samples layout ranking results in the Wilcoxon rank-sum / Mann–Whitney U test), and provides the desired robustness and ...
