What is another word for correlation matrix?
Pronunciation: [kˌɒɹɪlˈe͡ɪʃən mˈe͡ɪtɹɪks] (IPA) 
A correlation matrix is a statistical tool used to measure the relationship between two or more variables. Synonyms for the term correlation matrix include covariance matrix, correlation table, and correlation coefficient matrix. A covariance matrix is similar to a correlation matrix, but it measures the extent to which two variables vary together, both positively and negatively, without standardization. A correlation table is simply a matrix of correlation values between pairs of variables. Finally, a correlation coefficient matrix is a mathematical representation of the correlation between a set of variables, using a standardized value between -1 and 1 to indicate the strength of the relationship. All of these terms refer to the same concept of measuring the relationship between multiple variables.
