A complex hypothesis predicts the relationship among three or more variables.In this example,the variables are cough assist devices (independent),hospital admissions (dependent),and anxiety (dependent).A directional hypothesis states the nature of the interaction between two or more variables.In this example,the direction is indicated by the prediction "experience less anxiety." A complex hypothesis is correct,but the null hypothesis predicts no difference.This study has more than two variables (not simple)and indicates a direction and not just an association.A simple hypothesis has only two variables (this study has more than two),and there is a direction predicted (experiencing less anxiety and having fewer inpatient hospital admissions).
