What is the best way to report the standard error when publishing

loosely refer to the "10% error" cutoff as the point at which to stop

Right on, bro'!!!
Repeated measures means that you have multiple measurements on the same
individual. Usually, the same person measured at different time points. So if
you have N individuals and T times, then you can place your observations in an

In this layout, you can have 1 observation per cell o
