Scenario: The effect of Panax ginseng in lowering peripheral blood pressure As a researcher with an interest in hypertension, you embarked on a preliminary pre-post study to determine whether the herb, Panax ginseng can lower peripheral blood pressure in adults. In your study, participants (aged 35 years and above) were given the correct dosage of the herbal infusion. Before the participants were given the infusion, blood pressure was measured i.e. baseline blood pressure (bp_before). After the intake of infusion, blood pressure was measured again (bp_after). Study objectives To determine whether there is a difference in the mean blood pressure of the participants before and after consuming herbal infusion of P. ginseng. To determine if there is a difference in the mean blood pressure of males and females after the consumption of the herbal infusion of P. ginseng. Instructions Use the bpwide.dta dataset provided.
