State a problem about the relationship of age and gender to blood pressure. One problem between the relationship of age and gender to blood pressure is as you get older, people tend to exercise less.

Use your knowledge about the heart and the circulatory system to make a hypothesis about how the average blood pressure for a group of people would be affected by manipulating the age and gender of the group members.

How will you use the investigation screen to test your hypothesis? What steps will you follow? What data will you record? I think that as the age groups increase the average blood pressures will increase. By looking at all of the blood pressures after they have been taken you can see how they vary. By recording their medical history and factors you can see a pattern form.

Analyze the result of your experiment. Explain any patterns you observed.

Group one is age 11-17, group two 18-24, group three 25-34, group four 35-44 and group five 45-54.

In the females, regardless of age, 6 out of 50 subjects showed hypertension. 1 of these 6 was 30%overweight with a family history, 1 had a family history only, 1 had no history of anything, 1 consumed alcohol only, and 2 had high salt diets and were obese.

Males Group One- In the males 6 out of 50 subjects were hypertensive. 4 of them fell into the age group 45-54. 5 out of these six were obese and had a family history of hypertension.

Did the result of your experiment support your hypothesis? Why or why not? Based on your experiment, what conclusion can you draw about the relationship of age and gender to group blood pressure averages? Yes the information supported the hypothesis. Based on the results it shows that there were more cases of obesity in males than in females.

During the course of your experiment, did you...
