Question

1: Identify and describe the two general functions of statistics.

2: For this question, use the human body measurements page available at http://www.wolframalpha.com/examples/HumanBodyMeasurements.html. If our patient is a 5’10” male weighing 200 pounds, is the patient’s weight above or below the mean body weight for males?

3: You are the principal investigator for a small pilot study that is testing the impact of a medication therapy management program for patients with hypertension. Your patients have the following blood pressure measurements (systolic/diastolic) at the onset of the program: Male 125/80; Female 135/90; Female 135/100; Male 155/105; Female 165/95; Male 165/115; Female 150/100; Female 145/95; Male 195/130.

(a) Summarize this data visually. Organize it and present it as a graph, chart, or table.

(b) Calculate the mean and median systolic and diastolic blood pressures for all patients. How do the mean and median measures of systolic pressure compare to one another? How do the mean and median measures of diastolic pressure compare to one another? Which of these measures would be best to represent the data?

Answer 1

1.Answer

No, his weight(200pounds) is more than mean weight which is 165poundspounds

2.Answer

a)

Females                                            Males

135/90                                              125/80

135/100                                            155/105

165/96                                              165/115

150/100                                            195/130

145/95

b)

All systolics                                         All diastolic

135                                                            90

125                                                                  100

135                                                                  96

155                                                                  100

165                                                                  95

165                                                                  80

150                                                                  105

190                                                                  115

145                                                                  130

Calculate Mean of systolic pressures = Total observation/ No.of observation

                                                                    = 1365/9

                                                                    = 151.6

Calculate Mean of diastolic pressures = Total observation/ No.of observation

                                                                    = 911/9

                                                                    = 101.2      

Median of Systolic = 165 (The middle number)

Median of diastolic = 95 (The middle number)

It easy to compare systolic diastolic separately with males and females which shows who has more incidence of HTN (Hypertension.) Both measures can be represented in bar graph.
