Trend Lines

P

PA

We are conducting some research on welding and have some X-Y data plotted
where the Y axis corresponds to # of Inclusions, and the X axis is thickness.
I have done a Scatter Plot, and wish to add a Trend Line.
The question is: what is the difference between a Linear and Logarithmic
Trend Line.
Thanks
Paul
