Here’s a more detailed definition of the formula’s parameters: y (dependent variable) b (the slope of the regression line).

One of the best approaches in analyzing quantitive data in Excel is by running a simple linear regression. Got a different version? No problem, you can still follow the exact same steps. Linear regression analysis, in general, is a statistical method that shows or predicts the relationship between two variables or factors. Usually, this type of analysis is used when one is trying to find or establish the correlation between variables.

As you can see, the equation shows how y is related to x. The program does it in the background. The first part of making a simple linear regression graph in Excel is making a scatter plot. For convenience, edit the chart bounds and titles so the data points look centered on the chart. Click on any of the data points and right-click.

The trendline will tell you if the relationship of your variables is positive or negative. The simple linear regression is a good tool to determine the correlation between two or more variables.

Before, you have to mathematically solve it and manually draw a line closest to the data. Now, you can visually see the correlation between the variables without breaking a sweat.
