It is important to note that these non-effects are fairly precisely
estimated. This precision implies that if there had been
pronounced differences in outcomes between traditionalformat
and hybrid-format groups, it is highly likely that we
would have found them. In other words, we can be quite
confident that the actual effects were in fact close to zero, and
therefore differ from a hypothetical finding of “no significant
difference” that may result from excessively noisy data or an
insufficiently large sample.
