Introduction

Hi everyone! We are a group of students from Diagnostic Radiography and this is our blog made for our statistics project. Our group members consist of Nur Fadilah Mahyudin, Yi Xuan, Xin Hui, Yan Wei (Jodie), Hui Ting and Sabree.

We racked our heads over what research topic we should base our project on, because we wanted to find a topic in close relation to our future career where we could see ourselves applying the knowledge gathered from this project. After much deliberation, we chose to explore the hypothesis of whether one's blood pressure would be directly proportional to their height. The results of our findings would be extremely helpful towards angiography (examination of x-ray of blood or lymph vessels, carried out after introduction of a radio-opaque substance) and arterial surgeries, where timings of systolic and diastolic pressure have a great impact on success rates.

First off, let us guide you through what we were headed out to do.

What we want to know:
To find out the relationship between height and blood pressure (sub-divided to systolic and diastolic pressures).

Common medical words you will be seeing throughout the blog:

Systolic pressure
Highest arterial pressure during each heart beat.

Diastolic pressure
Lowest pressure within the arterial blood stream occurring during each heart beat.

How we carried out the collection of data:
We used 2 sphygmomanometers to collect blood pressures of our subjects, while 2 generic measuring tapes were used to measure their height. Collection of data was done within a day.

Range of data:
Height – 150 to 180 cm (both males and females)
Healthy systolic/diastolic pressure range – 120/80 mm Hg

Thus, this is the hypothesis we have come up with:

Height vs Diastolic & Systolic Pressures
H₀: There is no relationship between a person's height and his/her diastolic & systolic pressures.
H₁: There is a relationship between a person's height and his/her diastolic & systolic pressures.
