ABSTRACT
Like experiments using split-plot designs, experiments utilizing repeated measures designs have structures that involve more than one size of experimental unit. For example, a subject may be measured over time where time is one of the factors in the treatment structure of the experiment. By measuring the subject at several different times, the subject is essentially being “split” into parts (time intervals), and the response is measured on each part. The larger experimental unit is the subject or the collection of time intervals. The smaller unit is the interval of time during which the subject is exposed to a treatment or an interval just between time measurements.
