The Maxwell Distribution is a plot with the y-axis as the relative number of particles and the x-axis as the velocity. Each point on the curve tells us the relative number of particles or the fraction of particles that is at a certain velocity.  The curves would be bell-shaped which means that the middle part would be the highest part of the curve. This just means that the middle range of velocities for a certain element at a certain temperature would be its most likely velocity.
