Test validityTest validity is the extent to which a test (such as a chemical, physical, or scholastic test) accurately measures what it is supposed to measure. In the fields of psychological testing and educational testing, "validity refers to the degree to which evidence and theory support the interpretations of test scores entailed by proposed uses of tests". Although classical models divided the concept into various "validities" (such as content validity, criterion validity, and construct validity), the currently dominant view is that validity is a single unitary construct.
Impact evaluationImpact evaluation assesses the changes that can be attributed to a particular intervention, such as a project, program or policy, both the intended ones, as well as ideally the unintended ones. In contrast to outcome monitoring, which examines whether targets have been achieved, impact evaluation is structured to answer the question: how would outcomes such as participants' well-being have changed if the intervention had not been undertaken? This involves counterfactual analysis, that is, "a comparison between what actually happened and what would have happened in the absence of the intervention.
Beck Depression InventoryThe Beck Depression Inventory (BDI, BDI-1A, BDI-II), created by Aaron T. Beck, is a 21-question multiple-choice self-report inventory, one of the most widely used psychometric tests for measuring the severity of depression. Its development marked a shift among mental health professionals, who had until then, viewed depression from a psychodynamic perspective, instead of it being rooted in the patient's own thoughts.
Educational inequalityEducational inequality is the unequal distribution of academic resources, including but not limited to school funding, qualified and experienced teachers, books, and technologies, to socially excluded communities. These communities tend to be historically disadvantaged and oppressed. Individuals belonging to these marginalized groups are often denied access to schools with adequate resources. Inequality leads to major differences in the educational success or efficiency of these individuals and ultimately suppresses social and economic mobility.
Content validityIn psychometrics, content validity (also known as logical validity) refers to the extent to which a measure represents all facets of a given construct. For example, a depression scale may lack content validity if it only assesses the affective dimension of depression but fails to take into account the behavioral dimension. An element of subjectivity exists in relation to determining content validity, which requires a degree of agreement about what a particular personality trait such as extraversion represents.
Test preparationTest preparation (abbreviated test prep) or exam preparation is an educational course, tutoring service, educational material, or a learning tool designed to increase students' performance on standardized tests. Examples of these tests include entrance examinations used for admissions to institutions of higher education, such as college (e.g. the SAT and ACT), business school (the GMAT), law school (the LSAT or LNAT), medical school (the MCAT), BMAT, UKCAT and GAMSAT and graduate school (the GRE) and qualifying examinations for admission to gifted education programs.
QuizA quiz is a form of game or mind sport in which players attempt to answer questions correctly on one or several specific topics. Quizzes can be used as a brief assessment in education and similar fields to measure growth in knowledge, abilities, and skills, or simply as a hobby. They can also be televised for entertainment purposes, often in a game show format. The earliest known examples of the word date back to 1780; its etymology is unknown, but it may have originated in student slang.
RespondentA respondent is a person who is called upon to issue a response to a communication made by another. The term is used in legal contexts, in survey methodology, and in psychological conditioning. In legal usage, this specifically refers to the defendant in a legal proceeding commenced by a petition, or to an appellee, or the opposing party, in an appeal of a decision by an initial fact-finder. In the United States Senate, the two sides in an impeachment trial are called the management and the respondent.
Pairwise comparisonPairwise comparison generally is any process of comparing entities in pairs to judge which of each entity is preferred, or has a greater amount of some quantitative property, or whether or not the two entities are identical. The method of pairwise comparison is used in the scientific study of preferences, attitudes, voting systems, social choice, public choice, requirements engineering and multiagent AI systems. In psychology literature, it is often referred to as paired comparison. Prominent psychometrician L.
Convergent validityConvergent validity, for human cognition, especially within sociology, psychology, and other behavioral sciences, refers to the degree to which two measures that theoretically should be related, are in fact related. Convergent validity, along with discriminant validity, is a subtype of construct validity. Convergent validity can be established if two similar constructs correspond with one another, while discriminant validity applies to two dissimilar constructs that are easily differentiated.
