Narrower	biserial correlation coefficient, biserial correlation	A correlation coefficient in which one variable is many-valued and the other is dichotomous
	multiple correlation coefficient	An estimate of the combined influence of two or more variables on the observed (dependent) variable
	product-moment correlation coefficient, Pearson product-moment correlation coefficient	The most commonly used method of computing a correlation coefficient between variables that are linearly related
	split-half correlation, chance-half correlation	A correlation coefficient calculated between scores on two halves of a test
	tetrachoric correlation coefficient, tetrachoric correlation	A correlation coefficient computed for two normally distributed variables that are both expressed as a dichotomy
Broader	parametric statistic	Any statistic computed by procedures that assume the data were drawn from a particular distribution
Spanish	coeficiente de correlación, correlación
Catalan	coeficient de correlació, correlació
Adjectives	correlational	relating to or employing correlation
Verbs	correlate	bring into a mutual, complementary, or reciprocal relation
Verbs	correlate	to bear a reciprocal or mutual relation

English > *correlation*: 3 senses > noun 3, cognition
Meaning	A statistical relation between two or more variables such that systematic changes in the value of one variable are accompanied by systematic changes in the other.
Synonym	correlational statistics
Part of	correlational analysis	The use of statistical correlation to evaluate the strength of the relations between variables
Narrower	curvilinear correlation, nonlinear correlation, skew correlation	Any correlation in which the rates of change of the variables is not constant
	negative correlation, indirect correlation	A correlation in which large values of one variable are associated with small values of the other
	partial correlation	A correlation between two variables when the effects of one or more related variables are removed
	positive correlation, direct correlation	A correlation in which large values of one variable are associated with large values of the other and small with small
	spurious correlation	A correlation between two variables (e.g., between the number of electric motors in the home and grades at school) that does not result from any direct relation between them (buying electric motors will not raise grades) but from their relation to other variables
Broader	statistics	A branch of applied mathematics concerned with the collection and interpretation of quantitative data and the use of probability theory to estimate population parameters
Adjectives	correlational	relating to or employing correlation
Verbs	correlate	bring into a mutual, complementary, or reciprocal relation
