# Correlation and regression in Excel

Correlation is the statistical linear correspondence of variation between two variables. In finance, correlation is used in several facets of analysis including the calculation of portfolio.. Correlation in Excel - the basics Correlation is a measure that describes the strength and direction of a relationship between two variables. It is commonly used in statistics, economics and social sciences for budgets, business plans and the like. The method used to study how closely the variables are related is called correlation analysis

2. Select Regression and click OK. 3. Select the Y Range (A1:A8). This is the predictor variable (also called dependent variable). 4. Select the X Range(B1:C8). These are the explanatory variables (also called independent variables). These columns must be adjacent to each other. 5. Check Labels. 6. Click in the Output Range box and select cell A11. 7 The correlation coefficient (a value between -1 and +1) tells you how strongly two variables are related to each other. We can use the CORREL function or the Analysis Toolpak add-in in Excel to find the correlation coefficient between two variables. - A correlation coefficient of +1 indicates a perfect positive correlation. As variable X increases, variable Y increases

Simply select the source data and select 'Insert' and then in the 'Charts' section, select 'Scatter'. It seems that the data have a positive correlation Regression coefficients are independent of the change of origin but are not independent of the change of scale. Both the regression coefficients (b xy & b yx) have the same sign i.e. if bxy is positive then byx will also be positive and vice versa.
