Assume error for models when you extrapolate or try to find an output for an input outside the data range you examined
Assume that the farther outside the data range for inputs you tested the worse the predictions
Also the phrase next strength in pounds is vague
The neck can move a lot of directions and start at a lot of locations and end at a lot of different locations. Depending on where it starts and ends & other factors the strength will have a different measurement
2 of 2
I do not want to erase everything to change things to be out of 3 parts instead out of 2 parts
Strength measurements are dependent on specifying endurance level or the number of repetetions or time an action is performed for
It is often more appropriate to specify torque or some other unit instead of force for strength
If it is not an isometric contraction than strength values depend on the speed and direction or velocity of the movement relative to the direction of the force resisted
