MS Excel XY Scatter graph - Linear regression trend line
Hi,

I've plotted an XY scatter graph in MS excel, and plotted a linear regression trend line. How can I now calculate the difference between the data points I've entered and the linear regression line?

I'm trying to work out error between the data point and the linear regression trend line.

Thanks all.

S.
