In the context of examinations, the raw data might be described as a raw score (after test scores). If a scientist sets up a computerized thermometer which records the temperature of a chemical mixture in a test tube every minute, the list of temperature readings for every minute, as printed out on a spreadsheet or viewed on a computer screen ...
A scaled score is the result of some transformation(s) applied to the raw score, such as in relative grading. The purpose of scaled scores is to report scores for all examinees on a consistent scale. Suppose that a test has two forms, and one is more difficult than the other. It has been determined by equating that a score of 65% on form 1 is ...
Raw marks awarded in an exam are converted to UMS marks according to the difficulty of the exam paper and the performance of candidates. For example, one year a candidate may only need 62 raw marks to get an A grade (80%), but another year 62 marks may only be equivalent to a B grade (70%).
Comparison of the various grading methods in a normal distribution, including: standard deviations, cumulative percentages, percentile equivalents, z-scores, T-scores. In statistics, the standard score is the number of standard deviations by which the value of a raw score (i.e., an observed value or data point) is above or below the mean value of what is being observed or measured.
This curve is customized to each year's group of tests. For example, for the Regents Examination in Algebra I given January 2019, a raw score on the test of 27 points (out of 86; so, 31% correct) would be given a scaled score of 65, that is, considered "proficient" for the purposes of being awarded the Regents Diploma.

A test method is a method for a test in science or engineering, such as a physical test, chemical test, or statistical test. It is a definitive procedure that produces a test result. [ 1 ] In order to ensure accurate and relevant test results, a test method should be "explicit, unambiguous, and experimentally feasible.", [ 2 ] as well as ...
Anne Hathaway said in a new interview with V Magazine ahead of the release of her upcoming movie “The Idea of You” that chemistry tests have come a long way since her auditioning days in the ...
Since the score is a function of the observations, which are subject to sampling error, it lends itself to a test statistic known as score test in which the parameter is held at a particular value. Further, the ratio of two likelihood functions evaluated at two distinct parameter values can be understood as a definite integral of the score ...
