Question: In a psychosocial intervention project in a
university, training was carried out to increase the levels of
self-efficacy of a group of students (n=40). Using an academic
self-efficacy scale, the level of self-efficacy before and after
training was evaluated. We want to know if there are statistically
significant differences in the mean of self-efficacy at the
beginning and after training.
