A less common but … WebJun 7, 2014 · One limit would give you a t of 2.263 and the other limit would give you a t of -2.263. But when we come to effect sizes we need to use a noncentral t, which is a plan old t distribution that is not distributed around 0.00 and is not symmetric. The figure below shows a noncentral t distribution on 9 df with a noncentrality parameter of 1.8.
