A multivariate distribution is described as a distribution of multiple variables. <strong>Correlation</strong> is described as the analysis which lets us know the association or the absence of the relationship between two variables ‘x’ and ‘y’. On the other end, <strong>Regression</strong> analysis, predicts the value of the dependent variable based on the known value of the independent variable, assuming that average mathematical relationship between two or more variables.</p> <p>The difference between correlation and regression is one of the commonly asked questions in interviews. Moreover, many people suffer ambiguity in understanding these two. So, take a full read of this article to have a clear understanding on these two.</p> <h3>Comparison Chart</h3> <p></p> <table id="tablepress-384" class="tablepress tablepress-id-384"> <thead><tr class="row-1 odd"><th class="column-1">Basis for Comparison</th> <th class="column-2">Correlation</th> <th class="column-3">Regression</th> </tr> </thead> <tbody class="row-hover"><tr class="row-2 even"><td class="column-1">Meaning</td> <td class="column-2">Correlation is a statistical measure which determines co-relationship or association of two variables.</td> <td class="column-3">Regression describes how an independent variable is numerically related to the dependent variable.</td> </tr> <tr class="row-3 odd"><td class="column-1">Usage</td> <td class="column-2">To represent linear relationship between two variables.</td> <td class="column-3">To fit a best line and estimate one variable on the basis of another variable.</td> </tr> <tr class="row-4 even"><td class="column-1">Dependent and Independent variables</td> <td class="column-2">No difference</td> <td class="column-3">Both variables are different.</td> </tr> <tr class="row-5 odd"><td class="column-1">Indicates</td> <td class="column-2">Correlation coefficient indicates the extent to which two variables move together.</td> <td class="column-3">Regression indicates the impact of a unit change in the known variable (x) on the estimated variable (y).</td> </tr> <tr class="row-6 even"><td class="column-1">Objective</td> <td class="column-2">To find a numerical value expressing the relationship between variables.</td> <td class="column-3">To estimate values of random variable on the basis of the values of fixed variable.</td> </tr> </tbody> </table> <p></p> <p></p> <p></p> <table id="tablepress-384" class="tablepress tablepress-id-384" width="11"> <thead><tr class="row-1 odd"><th class="column-1"></th> <th class="column-2"></th> <th class="column-3"></th> </tr> </thead> <tbody class="row-hover"><tr class="row-2 even"><td class="column-1"></td> <td class="column-2"></td> <td class="column-3"></td> </tr> <tr class="row-3 odd"><td class="column-1"></td> <td class="column-2"></td> <td class="column-3"></td> </tr> <tr class="row-4 even"><td class="column-1"></td> <td class="column-2"></td> <td class="column-3"></td> </tr> <tr class="row-5 odd"><td class="column-1"></td> <td class="column-2"></td> <td class="column-3"></td> </tr> <tr class="row-6 even"><td class="column-1"></td> <td class="column-2"></td> <td class="column-3"></td> </tr> </tbody> </table>
