Is correlation matrix same as correlation?
A correlation matrix is simply a table which displays the correlation coefficients for different variables. The matrix depicts the correlation between all the possible pairs of values in a table. It is a powerful tool to summarize a large dataset and to identify and visualize patterns in the given data.
What is the function of correlation matrix?
A correlation matrix is used to summarize data, as an input into a more advanced analysis, and as a diagnostic for advanced analyses. Key decisions to be made when creating a correlation matrix include: choice of correlation statistic, coding of the variables, treatment of missing data, and presentation.
What is the difference between correlation matrix and covariance matrix?
Covariance and correlation are two terms that are opposed and are both used in statistics and regression analysis. Covariance shows you how the two variables differ, whereas correlation shows you how the two variables are related.

Example of a Correlation Matrix
Each cell in the table shows the correlation between two specific variables. For example, the highlighted cell below shows that the correlation between “hours spent studying” and “exam score” is 0.82, which indicates that they're strongly positively correlated.
