Research is done to see whether taking oral contraceptives increases women’s blood pressures. The blood pressures of women who take oral contraceptives are compared to the blood pressures of women who do not take oral contraceptive. A complicating factor is that the women who take oral contraceptives tend to be younger than the others. This must be taken into account because blood pressure increases with age. a) Response variable: (blood pressure, young age, taking oral contraceptives or not) b) Explanatory variable: (blood pressure, young age, taking oral contraceptives or not)) c) The confounding variable in this study is ( gender, age,taking oral contraceptives )
