I conducted an experiment, where all participants were tested for verbosity under a low and under a moderate stress situation. My primary hypothesis was "Low stress situations, compared to moderate stress situations, significantly reduce verbal capacity in participants." To explain possible individual differences, I did literature research to identify potential moderators. Based on this research I want to check if conscientiousness (as a personality trait) is explaining individual differences in verbosity when comparing situations, and also – in a separate analysis – I want to check if cultural background (as a contextual factor) may explain individual differences in verbosity. Due to mixed empirical findings, both explorative questions have to be formulated two-tailed without assuming any direction.
Since I'm not familiar with the formulation of explorative research questions, I would be glad to get some advice.
