Within-group Study
The repeated measures design (also known as a within-subjects design) uses the same subjects with every condition of the research, including the control. For instance, repeated measures are collected in a longitudinal study in which change over time is assessed. Other studies compare the same measure under two or more different conditions. For instance, to test the effects of caffeine on cognitive function, a subject's math ability might be tested once after they consume caffeine and another time when they consume a placebo.

Famous quotes containing the word study:
“It’s worth living abroad to study up on genteel and delicate manners. The maid smiles continuously; she smiles like a duchess on a stage, while at the same time it is clear from her face that she is exhausted from overwork.”
—Anton Pavlovich Chekhov (1860–1904)
