Adjective
/tɛtrəˈkɔːrɪk/
The term tetrachoric refers to statistical methods or models that involve four categories or classes. It is often used in the context of tetrachoric correlation, which is a statistic used to estimate the correlation between two dichotomous variables (variables with two possible categories). This term is primarily used in academic and mathematical contexts, particularly in statistics, psychometrics, and social sciences.
Frequency of Use: The word "tetrachoric" is not common in everyday conversation or writing and is mainly found in specialized academic literature and discussions.
Oral vs. Written Context: It is predominantly used in written contexts, such as research papers, articles, and textbooks.
Tetrachoric correlations are often utilized in psychometric studies to understand the relationship between binary variables.
Tetrachoric correlations sont souvent utilisés dans les études psychométriques pour comprendre la relation entre les variables binaires.
The researchers calculated the tetrachoric coefficients to evaluate the latent traits of the participants.
Les chercheurs ont calculé les coefficients tétrachoriques pour évaluer les traits latents des participants.
In her thesis, she discussed the implications of using tetrachoric models for data analysis.
Dans sa thèse, elle a discuté des implications de l'utilisation de modèles tétrachoriques pour l'analyse des données.
The term "tetrachoric" does not have a wide range of idiomatic expressions associated with it, as it is a specialized term primarily used in technical contexts. However, within its narrow field, it can relate to several phrases about statistical analysis. Here are a few examples:
Tetrachoric analysis sheds light on the complexity of behavioral assessments.
L'analyse tétrachorique éclaire la complexité des évaluations comportementales.
Researchers often debate the reliability of tetrachoric estimates when dealing with non-normal distributions.
Les chercheurs débattent souvent de la fiabilité des estimations tétrachoriques lorsqu'ils traitent des distributions non normales.
The application of tetrachoric techniques is essential in effective test construction.
L'application des techniques tétrachoriques est essentielle dans la construction efficace de tests.
The word "tetrachoric" is derived from the Greek roots "tetra," meaning four, and "choros," meaning space or region. The term is indicative of the four-category framework often discussed in statistical modeling.
Synonyms: - Tetrachoric correlation (when referring to the statistical context) - Tetrachoric coefficient
Antonyms: - Non-tetrachoric (not applicable as a direct antonym but can imply a lack of such correlation) - Dichotomous (when considering terms that refer to binary variables rather than the analysis of correlation)
In statistical methods, terms often lack direct antonyms since they describe specific processes or analyses rather than contrasting actions.
