Noun phrase
/kɔːrəˈleɪʃən ˈnʌmbər/
The term "correlation number" refers to a statistical measure that describes the extent to which two variables fluctuate together. It typically indicates the strength and direction of a linear relationship between variable pairs and is often represented by the correlation coefficient (often denoted as "r"). The correlation number ranges from -1 to +1, where -1 indicates a perfect negative correlation, 0 indicates no correlation, and +1 indicates a perfect positive correlation.
This term is most commonly used in written contexts, such as academic articles, statistical reports, and research papers. Its usage is frequent in fields like statistics, psychology, economics, and data science.
The correlation number between study time and exam scores is significantly positive.
(El número de correlación entre el tiempo de estudio y las calificaciones de los exámenes es significativamente positivo.)
Researchers often calculate the correlation number to analyze the relationship between different factors.
(Los investigadores a menudo calculan el número de correlación para analizar la relación entre diferentes factores.)
A correlation number close to zero suggests little to no linear relationship between the variables.
(Un número de correlación cercano a cero sugiere poca o ninguna relación lineal entre las variables.)
While "correlation number" is more prevalent in specialized contexts, there are a few idioms and phrases relevant to relationships and connections between variables. Here are some examples:
"Correlation does not imply causation."
(La correlación no implica causalidad.)
This expression warns that just because two events correlate, it doesn't mean that one causes the other.
"They have a strong correlation."
(Tienen una fuerte correlación.)
Used to describe events, ideas, or variables that strongly relate or influence each other.
"The data shows a weak correlation at best."
(Los datos muestran una correlación débil, como mucho.)
Indicates that data is not supportive of a strong relationship between the variables analyzed.
"There is a notable correlation between exercise and mental health."
(Hay una correlación notable entre el ejercicio y la salud mental.)
Points out the link between physical activity and mental well-being.
The word "correlation" comes from the Latin root "correlat-", which means "to relate together". The suffix "-tion" indicates the action or condition of relating. The term has been in use since the early 19th century in statistical contexts, emphasizing the dependency and connection between different elements.
