I have fixation points x, y for n participants. How do I determine the linearity of the points per participant. I have attached the file with data.
I had participants who were reading a paragraph on paper, screen and mobile device. I want to compare the linearity when reading from the different platforms. I used an eye tracker to record the eye movements and the data it produces is in form of fixation points x, y. Fixation points are where participants looked when reading. In the attached file, there are fixation points x, y for 2 participants. I must compare the linearity betwwen the two when they read the same paragraph.
