How would this be different from simply increasing the size of the control group? Or subdivide the control into N groups of sufficient size in order to more effectively visualize the variation?
- hcarvalhoalves 12y agoIf you just have one big control, this still does not tell about variance inside the control. You can subdivide the control in N groups, but I think you quickly increase the noise to signal ratio. A control group split into two is a good compromise, and intuitive to reason about, like the author points.
