Factors affecting blood pressure differ users and nonusers

Reference no: EM13119613

Suppose a medical researcher compares the average blood pressures of women who take oral contraceptives to the blood pressures of women who do not.

a. Is blood pressure a categorical variable or a quantitative variable and which graph(s) would be most appropriate to use to display the data?

b. Is oral contraceptive use (or not) a categorical variable or a quantitative variable and which graph(s) would be most appropriate to use to display the data?

c. What variables that affect blood pressure might confuse the comparison of average blood pressures for users and nonusers? That is, what factors affecting blood pressure might differ for users and nonusers. Explain.
