A study was conducted in which healthy women (aged 35 to 55) received either a new blood pressure medication or a placebo pill for 5 months. The results indicated that those women who took the actual medication experienced a significantly greater decrease in systolic blood pressure (average decrease = 17 mm Hg) as compared to those who took the placebo (average decrease = 2 mm Hg).

Coding for study variables:

• MED 1 = medication; 2= placebo
• SBP systolic blood pressure [mm Hg (millimeters of mercury)]
