Uses of A Repeated Measures Design
- Conduct an experiment when few participants are available: The repeated measure design reduces the variance of estimates of treatment-effects, allowing statistical inference to be made with fewer subjects.
- Conduct experiment more efficiently: Repeated measures designs allow many experiments to be completed more quickly, as only a few groups need to be trained to complete an entire experiment. For example, there are many experiments where each condition takes only a few minutes, whereas the training to complete the tasks take as much, if not more time.
- Study changes in participants’ behavior over time: Repeated measures designs allow researchers to monitor how the participants change over the passage of time, both in the case of long-term situations like longitudinal studies and in the much shorter-term case of order effects.

Famous quotes containing the words repeated, measures and/or design:
“When we awoke, we found a heavy dew on our blankets. I lay awake very early, and listened to the clear, shrill ah, te te, te te, te of the white-throated sparrow, repeated at short intervals, without the least variation, for half an hour, as if it could not enough express its happiness. Whether my companions heard it or not, I know not, but it was a kind of matins to me, and the event of the forenoon.”
—Henry David Thoreau (1817–1862)
“There are other measures of self-respect for a man, than the number of clean shirts he puts on every day.”
—Ralph Waldo Emerson (1803–1882)
“Teaching is the perpetual end and office of all things. Teaching, instruction is the main design that shines through the sky and earth.”
—Ralph Waldo Emerson (1803–1882)
