    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.

    In statistics, a rank test is any test involving ranks. Rank tests are related to permutation tests. Motivation

  4. Predictive validity - Wikipedia

    en.wikipedia.org/wiki/Predictive_validity

    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 ...

  5. Rank correlation - Wikipedia

    en.wikipedia.org/wiki/Rank_correlation

    Dave Kerby (2014) recommended the rank-biserial as the measure to introduce students to rank correlation, because the general logic can be explained at an introductory level. The rank-biserial is the correlation used with the Mann–Whitney U test, a method commonly covered in introductory college courses on statistics. The data for this test ...

  6. Wilcoxon signed-rank test - Wikipedia

    en.wikipedia.org/wiki/Wilcoxon_signed-rank_test

    The Wilcoxon signed-rank test is a non-parametric rank test for statistical hypothesis testing used either to test the location of a population based on a sample of data, or to compare the locations of two populations using two matched samples. [1] The one-sample version serves a purpose similar to that of the one-sample Student's t-test. [2]

  7. Percentile rank - Wikipedia

    en.wikipedia.org/wiki/Percentile_rank

    The figure illustrates the percentile rank computation and shows how the 0.5 × F term in the formula ensures that the percentile rank reflects a percentage of scores less than the specified score. For example, for the 10 scores shown in the figure, 60% of them are below a score of 4 (five less than 4 and half of the two equal to 4) and 95% are ...

  8. Mann–Whitney U test - Wikipedia

    en.wikipedia.org/wiki/Mann–Whitney_U_test

    The Mann–Whitney test (also called the Mann–Whitney–Wilcoxon (MWW/MWU), Wilcoxon rank-sum test, or Wilcoxon–Mann–Whitney test) is a nonparametric statistical test of the null hypothesis that, for randomly selected values X and Y from two populations, the probability of X being greater than Y is equal to the probability of Y being greater than X.

  9. Norm-referenced test - Wikipedia

    en.wikipedia.org/wiki/Norm-referenced_test

    A norm-referenced test does not seek to enforce any expectation of what test takers should know or be able to do. It measures the test takers' current level by comparing the test takers to their peers. A rank-based system produces only data that tell which students perform at an average level, which students do better, and which students do worse.
