Cross-sectional research is a research method often used in developmental psychology, but also utilized in many other areas including social science and education. This type of study utilizes different groups of people who differ in the variable of interest, but share other characteristics such as socioeconomic status, educational background ...
In psychology the term "conceptual definition" is used for a concept variable. ... overall the "g" or general intelligence factor is relatively supported by research ...
The CFA is also called as latent structure analysis, which considers factor as latent variables causing actual observable variables. The basic equation of the CFA is X = Λξ + δ where, X is observed variables, Λ are structural coefficients, ξ are latent variables (factors) and δ are errors.
An operational definition is designed to model or represent a concept or theoretical definition, also known as a construct.Scientists should describe the operations (procedures, actions, or processes) that define the concept with enough specificity such that other investigators can replicate their research.
The book discusses the extent to which psychology can measure mental attributes such as intelligence and examines the philosophical issues that arise from such attempts. The book examines three major models within psychometrics; classical test theory/true scores, latent variables/item response theory and representational measurement theory ...
Operationalization is the scientific practice of operational definition, where even the most basic concepts are defined through the operations by which we measure them. The practice originated in the field of physics with the philosophy of science book The Logic of Modern Physics (1927), by Percy Williams Bridgman, whose methodological position is called "operationalism".
The use of the term conceptual framework crosses both scale (large and small theories) [4] [5] and contexts (social science, [6] [7] marketing, [8] applied science, [9] art [10] etc.). The explicit definition of what a conceptual framework is and its application can therefore vary. Conceptual frameworks are beneficial as organizing devices in ...
Construct validity concerns how well a set of indicators represent or reflect a concept that is not directly measurable. [1] [2] [3] Construct validation is the accumulation of evidence to support the interpretation of what a measure reflects.
