distribution were calculated. Moreover, other statistical evidence
was calculated: counterfactual scenario (Student t-test for independent
samples), with the aim of detecting whether there is
any difference for waste generation in the two periods, and a
one-way ANOVA with repeated measures to know whether the factor
‘‘day of the week” affects generation. From the daily generation
data and the number of users of the University, the generation rate
(GR) was calculated. The number of users was 17.792 people which
correspond to the total number of staff and students of the University
in 2013. It was the same for the two periods and included
undergraduates, postgraduates, researchers, technicians, professors
and administration staff.
