![]() ![]() Disable the Gridlines option to give the chart a clean look.Add the Chart Title, for example, “Scatter Plot of Stock Price vs, Earnings Per Share”.Here, it is “Stock Price” and “Earnings Per Share”. In addition to the default selection, enable the Axes Title to provide axes names.Now, we’ll format the Scatter plot using the Chart Elements option. Select the C4:D16 cells with the numerical data > go to the Insert tab > in the Charts group, and select the Scatter option. Here, we want to plot a Scatter graph to find the correlation coefficient between “Stock Price”, and “Earnings Per Share”. Let’s consider the financial information of “CapitalWise Inc.” which contains the “Month”, “Stock Price”, and “Earnings Per Share” columns. In this section, we’ll describe the steps on how to find the correlation coefficient in an Excel Scatter Plot. How to Find Correlation Coefficient in Excel Scatter Plot: 3 Easy Steps This means that we cannot conclude that changes in one variable cause the other variable to change. It’s important to note that correlation only indicates the degree of association between two variables, and doesn’t establish a causal relationship. Here, increasing the “Number of Employees” has no correlation to the “Gross Margin”. For example, as the “Interest” rate increases the “Bond Price” decreases.Ī coefficient value of zero shows a line parallel to the horizontal axis, which indicates no correlation. In this scenario, as the “Revenue” variable increases the “Net Income” variable also increases.Ī negative coefficient gives a negative (downward) slope on a graph. The positive or negative sign of the correlation coefficient shows the direction of the relationship.Ī positive coefficient results in a positive (upward) slope on a graph. The magnitude (absolute value) of the correlation coefficient determines the strength of the relationship. The degree of correlation between two variables is the correlation coefficient. Interpreting Correlation Coefficient in Excel The formula to calculate the Pearson correlation coefficient (r) for the two variables x and y is given below. In simple terms, it is the ratio of the covariance and product of the standard deviation of the two variables. Pearson Correlation Coefficient measures the linear correlation between two variables. A coefficient of 0 means there is no correlation between the variables.An absolute positive correlation is represented by +1 while an absolute negative correlation is shown by -1.The coefficient can have a value ranging from -1 to +1. It also indicates whether there is a positive or negative relationship between the two variables.Ĭorrelation Coefficient is a numerical value that measures the degree of correlation between two variables.
