Lecture 7: One-Way Repeated Measures ANOVA
Repeated measures designs
We often use an experimental design in which
measurements on a single DV are repeated a number of times within
the same subject.
Such designs in which subjects are crossed with at least
one experimental factor are called repeated-measures designs.
The simplest experiment of this kind may be a before- and after-
treatment design (two conditions)
One-way repeated measures design
N subjects are measured on a single DV under K conditions or levels of
a single IV or factor.
Example: One-way repeated measures design
Four migraine sufferers were asked to record the duration
of their migraine headaches. After the baseline recording, during
which no training was given, each subject had a six-week period of
relaxation training. We would like to know if the relaxation therapy
can help to relieve the migraine. The dependent variable is the
duration (hours/week) of headaches recorded at the third and sixth
week of the therapy.
We may be interested to find out if the relaxation training
is effective in reducing the duration of migraine headaches.
