Duration of eye contact is the only dependent variable that represents a ratio scale of measurement because it has a true zero point (i.e. no eye contact for a duration of zero seconds). The other variables either have a dichotomous (present/absent) or ordinal (rank ordering) scale of measurement. The ratings of intimacy of eye contact may have an interval scale of measurement, but without knowing the specific scale used, it is impossible to determine if it is a ratio scale.
