Hello,
For my excel project, I'm plotting data from a profilometer program.
What I'm trying to do is get a trendline for my given data, put the equation for the trendline and plug in the X values, and compare the given data to the trendline inputted data.
The problem is that for whatever reason, the trendline equation is incorrect.
I plotted the data I have with the trendline on top of it, and then plotted X vs. the Trendline data; it comes out completely different.
I've attached my file, can anyone see what the hell is going on?
[Note: there is a lot of data so please be patient as it does freeze up computers for a minute or two
Also since my file was too big, I saved it as a binary excel file (.xlsb) but since you don't allow that on your site, I renamed it to a .xls file; It will say it may be corrupted but opens fine]
