This definition is slightly different from the ECDF, which includes the points (u(i), i/n). In the left frame of Figure 5, we display the q-q plot of the 5 points in Table 1. In the right two frames of Figure 5, we display the q-q plot of the same batch of numbers used in Figure 2. In the final frame, we add the diagonal line y = x as a point of reference.
