this is the study:
A study investigated the effect of mindfulness training on perceived levels of stress. 15 participants (7 male, 8 female) were recruited and divided into two groups, only one of which took part in a 5-day mindfulness course. Stress levels of all participants were measured at three time points (day 1, day 3, and day 5).
1. a) Identify and state the variables and the design of this study
the design of the study would be between-subject
but I am little confused about the variables of the study!
Variables: stress levels and mindfulness training ?
