I'm trying to test correlation between 2 sets of data and ran both a simple linear regression in Excel and built a scatterplot. Though new to regression, I feel like my 2 outputs tell different stories.
The regression (attached) has a Adjusted R Square of -0.0025, indicating almost no correlation. However, the scatterplot (also attached) looks like it shows some degree of negative correlation despite outliers. I'm confused why these look different and how to draw my conclusion about the usefulness of comparing these data.
Any help appreciated.
