I am conducting a research study where subjects are sitting in a simulated wave motion cabin on top of a 6 DOF device to try to get them sick. With this I am having the subjects complete some cognitive tasks during the ride. One of the tasks is having the subjects hold a board and try to keep it level to earth. Subjects are given the example that is a glass of water is sitting on top of the board you do not want it to spill. There is an IMU placed on the board gathering their inputs. I am trying to figure out what the best way is to analyze how well the subjects did on keeping the board level. I tried RMS error and it was really messy. Any advice would be helpful. I attached a figure of the subject IMU inputs as well as reference IMU that is capturing the movement of the simulator. ![](https://www.mathworks.com/matlabcentral/answers/uploaded_files/1138225/image.jpeg)

The RMS is a single number. Exactly what about that number tells you whether it (the RMS metric) "worked out" or "wasn't working very well"?
