Data are the self esteem score of 12 individuals enrolled in 2
successive short-term trials (4 weeks) - control (placebo) and special diet
trials.
The self esteem score was recorded at three time points: at the beginning
(t1), midway (t2) and at the end (t3) of the trials.
The same 12 participants are enrolled in the two different trials with
enough time between trials.
Two-way repeated measures ANOVA can be performed in order to determine
whether there is interaction between time and treatment on the self
esteem score.
