  Asteroseismology is witnessing a revolution thanks to high-precise
asteroseismic space data (MOST, CoRoT, Kepler, BRITE), and their large
ground-based follow-up programs. Those instruments have provided an
unprecedented large amount of information, which allows us to scrutinize its
statistical properties in the quest for hidden relations among pulsational
and/or physical observables. This approach might be particularly useful for
stars whose pulsation content is difficult to interpret. This is the case of
intermediate-mass classical pulsating stars (i.e. gamma Dor, delta Scuti,
hybrids) for which current theories do not properly predict the observed
oscillation spectra. Here we establish a first step in finding such hidden
relations from Data Mining techniques for these stars. We searched for those
hidden relations in a sample of delta Scuti and hybrid stars observed by CoRoT
and Kepler (74 and 153, respectively). No significant correlations between
pairs of observables were found. However, two statistically significant
correlations emerged from multivariable correlations in the observed seismic
data, which describe the total number of observed frequencies and the largest
one, respectively. Moreover, three different sets of stars were found to
cluster according to their frequency density distribution. Such sets are in
apparent agreement with the asteroseismic properties commonly accepted for A-F
pulsating stars.
