Instructions: This correlation matrix calculator will provide you with a correlation matrix for a given set of samples. Please type in the box below two or more samples. Please press '\' to start a new sample.
More About the Correlation Matrix
A Correlation Matrix is a table in which the pairwise correlations between several variables are conveniently organized in a matrix form. The value in the ith row an jth column corresponds to the correlation between the variables \(X_i\) and \(X_j\).
Since \(corr(X_i, X_j) = corr(X_j, X_i)\), then the correlation matrix is symmetric, and for that reason, in order to not to be redundant, the correlation matrix only reports the values from the diagonal and up. For other correlation operations, you can compute a correlation coefficient showing all the steps, or you can use this critical correlation calculator.
