Launch Angle Distributions
People often reference average launch angle as a reason why hitting the ball at good angles shouldn't be a priority for hitters because often a good hitter and a not so good hitter can have the exact same average launch angle. The problem with that is that this doesn't take the spread into consideration. A good player will typically have a smaller standard deviation of launch angle versus a not so good hitter. Simply put, they are hitting it at good angles more consistently. Below I believe is a decent visualization of that. The bars are bins of 5 degree windows for launch angles.
