I figured out the first part...I went and re did the lab again and got the max with completely different data. This second part though I am getting very off data and I think its because I'm not measuring right with the magnetic sensor...when measuring the magnetic inclination how should I hold the sensor?

For the inclination, you need to start with the sensor horizontal and aligned with the max field from the first part, i.e. magnetic north. Then rotate the sensor in the vertical plane through that.
 
I did it three different times haha, all different ways, can you show me a picture of what it might look like?

3D pictures are difficult to draw well, and I'm not even good at 2D ones.
I thought my verbal description was easy enough to follow.
How about you post a picture of what you think I'm saying, or provide your own paraphrasis?
 
I actually think I figured it out...3 percent error seems reasonable too, thanks a lot for everything though!

It's not a statistic for which percentage error is appropriate. It's the absolute error that matters. (Though I guess you could express it as a percentage of 360 degrees.)
