Ipsative
In psychology, ipsative questionnaires (; from Latin: ''ipse'', 'of the self') are those where the sum of scale scores from each respondent adds to a constant value. Sometimes called a forced-choice scale, this measure contrasts Likert-type scales in which respondents score—often from 1 to 5—how much they agree with a given statement (see also norm-referenced test). In psychology While mean scores from Likert-type scales can be compared across individuals, scores from an ipsative measure cannot. To explain, if an individual was equally extroverted and conscientious and was assessed on a Likert-type scale, each trait would be evaluated singularly, i.e. respondents would see the item "I enjoy parties" and agree or disagree with it to whatever degree reflected their preferences. If the same traits were evaluated on an ipsative measure, respondents would be forced to choose between the two, i.e. a respondent would see the item "Which of these do you agree with more strongly? a ...

Value-added Modeling
Value-added modeling (also known as value-added measurement, value-added analysis and value-added assessment) is a method of teacher evaluation that measures the teacher's contribution in a given year by comparing the current test scores of their students to the scores of those same students in previous school years, as well as to the scores of other students in the same grade. In this manner, value-added modeling seeks to isolate the contribution, or value added, that each teacher provides in a given year, which can be compared to the performance measures of other teachers. VAMs are considered to be fairer than simply comparing student achievement scores or gain scores without considering potentially confounding context variables like past performance or income. It is also possible to use this approach to estimate the value added by the school principal or the school as a whole. Critics say that the use of tests to evaluate individual teachers has not been scientifically validated ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Criterion-referenced Assessment
A criterion-referenced test is a style of test which uses test scores to generate a statement about the behavior that can be expected of a person with that score. Most tests and quizzes that are written by school teachers can be considered criterion-referenced tests. In this case, the objective is simply to see whether the student has learned the material. Criterion-referenced assessment can be contrasted with norm-referenced assessment and ipsative assessment. Criterion-referenced testing was a major focus of psychometric research in the 1970s. Definition of ''criterion'' A common misunderstanding regarding the term is the meaning of ''criterion''. Many, if not most, criterion-referenced tests involve a cutscore, where the examinee passes if their score exceeds the cutscore and fails if it does not (often called a mastery test). The ''criterion'' is not the cutscore; the criterion is the domain of subject matter that the test is designed to assess. For example, the criterio ...

Likert Scale
A Likert scale ( , commonly mispronounced as ) is a psychometric scale commonly involved in research that employs questionnaires. It is the most widely used approach to scaling responses in survey research, such that the term (or more fully the Likert-type scale) is often used interchangeably with ''rating scale'', although there are other types of rating scales. The scale is named after its inventor, psychologist Rensis Likert. Likert distinguished between a scale proper, which emerges from collective responses to a set of items (usually eight or more), and the format in which responses are scored along a range. Technically speaking, a Likert scale refers only to the former. The difference between these two concepts has to do with the distinction Likert made between the underlying phenomenon being investigated and the means of capturing variation that points to the underlying phenomenon. When responding to a Likert item, respondents specify their level of agreement or disagree ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Norm-referenced Test
A norm-referenced test (NRT) is a type of test, assessment, or evaluation which yields an estimate of the position of the tested individual in a predefined population, with respect to the trait being measured. Assigning scores on such tests may be described as relative grading, marking on a curve (BrE) or grading on a curve (AmE, CanE) (also referred to as curved grading, bell curving, or using grading curves). It is a method of assigning grades to the students in a class in such a way as to obtain or approach a pre-specified distribution of these grades having a specific mean and derivation properties, such as a normal distribution In statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is : f(x) = \frac e^ The parameter \mu ... (also called Gaussian distribution).

Steve Blinkhorn
Stephen F. Blinkhorn, CPsychol, FBPsS (born 1949) is a British occupational psychologist and psychometrician (based in Hertfordshire), who continues to contribute to psychology and psychometric testing. Blinkhorn is known for publishing a number of papers, many of which have taken the form of book reviews for ''Nature'' magazine, including: 'Willow, Titwillow, Titwillow' (a review of Herrnstein and Murray's ''The Bell Curve''); 'What skulduggery?' (a review of Stephen Jay Gould's 'The Mismeasure of Man'); and 'A gender bender' (a critique on Paul Irwing and Richard Lynn's paper on sex and intelligence). Other papers have argued about the inappropriate use of the Rasch model, and the misuse of personality tests. Life and career After attending grammar school, Blinkhorn attended St Edmund Hall, Oxford. Academia From 1973 to 1987, he developed and ran one of the first postgraduate studies in Occupational Psychology (in Britain) at what was then Hatfield Polytechnic, now the ...

Two-alternative Forced Choice
Two-alternative forced choice (2AFC) is a method for measuring the sensitivity of a person, child or infant, or animal to some particular sensory input, stimulus, through that observer's pattern of choices and response times to two versions of the sensory input. For example, to determine a person's sensitivity to dim light, the observer would be presented with a series of trials in which a dim light was randomly either in the top or bottom of the display. After each trial, the observer responds "top" or "bottom". The observer is not allowed to say "I do not know", or "I am not sure", or "I did not see anything". In that sense the observer's choice is forced between the two alternatives. Both options can be presented concurrently (as in the above example) or sequentially in two intervals (also known as two-interval forced choice, 2IFC). For example, to determine sensisitivity to a dim light in a two-interval forced choice procedure, an observer could be presented with series of trials ...

Standardized Test
A standardized test is a test that is administered and scored in a consistent, or "standard", manner. Standardized tests are designed in such a way that the questions and interpretations are consistent and are administered and scored in a predetermined, standard manner. Any test in which the same test is given in the same manner to all test takers, and graded in the same manner for everyone, is a standardized test. Standardized tests do not need to be high-stakes tests, time-limited tests, or multiple-choice tests. A standardized test may be any type of test: a written test, an oral test, or a practical skills performance test. The questions can be simple or complex. The subject matter among school-age students is frequently academic skills, but a standardized test can be given on nearly any topic, including driving tests, creativity, athleticism, personality, professional ethics, or other attributes. The opposite of standardized testing is ''non-standardized testing'', in w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Psychometrics
Psychometrics is a field of study within psychology concerned with the theory and technique of measurement. Psychometrics generally refers to specialized fields within psychology and education devoted to testing, measurement, assessment, and related activities. Psychometrics is concerned with the objective measurement of latent constructs that cannot be directly observed. Examples of latent constructs include intelligence, introversion, mental disorders, and educational achievement. The levels of individuals on nonobservable latent variables are inferred through mathematical modeling based on what is observed from individuals' responses to items on tests and scales. Practitioners are described as psychometricians, although not all who engage in psychometric research go by this title. Psychometricians usually possess specific qualifications such as degrees or certifications, and most are psychologists with advanced graduate training in psychometrics and measurement theory. I ...

Psychological Assessment
Psychological evaluation is a method to assess an individual's behavior, personality, cognitive abilities, and several other domains. A common reason for a psychological evaluation is to identify psychological factors that may be inhibiting a person's ability to think, behave, or regulate emotion functionally or constructively. It is the mental equivalent of physical examination. Other psychological evaluations seek to better understand the individual's unique characteristics or personality to predict things like workplace performance or customer relationship management.
