I have comparison readings of equipment, so I will take the difference between the two columns. The question is, what is the best way of averaging those differences since I will get positive and negative differences in the comparison readings. For instance:
A B C (Difference)
3.4 3.3 0.1
3.5 3.6 -0.1
3.7 4.0 -0.3
3.8 3.8 0.0
3.5 3.2 0.3
If you combine all of the differences, the average is 0.0, but if I use the average deviation, it gives me +0.2.
Any suggestions on the best way of providing the mean deviation?
Thanks
