A methodology for analyzing the variability of the tidal fluctuation in a specific area is proposed in this work. The idea is to consider intervals determined by the minimum and maximum height reached by the tides in a day. Thus, the theoretical aim is to develop hypothesis tests about the variance of one or more interval-valued random elements (i.e., random intervals). Some simulations showing the empirical behavior and consistency of the proposed tests are carried out by considering different models. Finally, the procedure is applied to a real-life study concerning the fluctuation of tides in the port of Gijón (Asturias).
