There is practically no connection with the values in the column x3. There is a strong feedback between x1 and x2. If the coordinates are the same, the value 1 is output.īetween the values of y and x1 is found the strong direct connection. At the intersection of rows and columns there are the correlation coefficients.
After pressing OK, the correlation matrix appears in the output range. The size of the range will be determined automatically. The output interval is the reference to the cell from which the matrix is to be built. The grouping - by columns (analyzed data are grouped into columns). The input interval is the range of cells with values. Click OK and set the parameters for data analysis. In the analysis tools list, zou need to select «Correlation». If the button is not available, you need to add it («Excel Options»- «Add-ins»). On the «Data» tab in the «Analysis» group, we need to open the «Data analysis» package (for the 2007 version). The matrix of correlation coefficients in Excel is constructed using the «Correlation» tool from the «Data analysis» package. It makes sense to build it for several variables. The correlation matrix is the table, at the intersection of rows and columns of which are the correlation coefficients between the corresponding values. The matrix of paired correlation coefficients in Excel The interconnection is straight: grows y - grows x, decreases y - decreases x. There is a strong interconnection between y and x, because the lines run almost parallel to each other. We show the values of the variables on the chart: The arguments of the function are an array of values of y and an array of values of x: You need to call the function wizard and to find the right one. We calculate the coefficient of pair correlation in Excel with its help. The built-in CORREL function allows you to avoid of complex calculations. The strong direct link is defined between the variables. It remains to calculate the quotient (the numerator and denominator are already known). Find the sum of the values in the received columns (using the AUTO-SUM function) and multiply these values. To calculate the difference denominator of y and y-average, x and x-average. Find the sum of the values in this column. 
You need multiply now the differences found:. Calculate the difference between each y and y mean, each x and x medium. Find the mean values of the variables using the AVERAGE function:. To make it easier to understand, we will break it into several simple elements. The formula of the correlation coefficient looks like that: It is necessary to find the strength (strong / weak) and the direction (direct / inverse) of the connection between them. Y is an independent variable, x is an independent variable. Let`s consider the example to the methods of calculating the correlation coefficient, the particular qualitie of the direct and inverse relationship between the variables.
