Repeated measures refer to the observations taken on the same subject (plant, animal, person, etc). There is usually a variation among the subjects, which is modeled by random effects. Here is an example. A completely randomized design with a single factor (with fertilizer or without). Each treatment is applied to three plants and the root length of each plant is measured on five occasions (wee...

A repeated-measures design is one in which multiple, or repeated, measurements are made on each experimental unit. The experimental unit could be a person or an animal, and repeated measurements might be taken serially in time, such as in weekly systolic blood pressures or monthly weights. The repeated assessments might be measured under different experimental conditions. Repeated measurements ...

1 The aim of the present study was to investigate the effects of motivating and 2 oudeterous (neither motivating nor demotivating) synchronous music on 400-metre 3 sprint performance while controlling for the potential confound of pre-performance 4 mood. A panel of volunteer Caucasian males (n = 20; mean age = 20.5, s = 1.2 years) 5 rated the motivational qualities of 32 musical selections usin...

Recently, new tests for main and simple treatment effects, time effects, and treatment by time interactions in possibly high-dimensional multigroup repeated-measures designs with unequal covariance matrices have been proposed. Technical details for using more than one between-subject and more than one within-subject factor are presented in this article. Furthermore, application to electroenceph...
