Hence after analysing the data, we had rejected our null hypothesis. So we have proven our research hypothesis, which is:

THERE IS A POSTITVE RELATIONSHIP BETWEEN BLOOD PRESSURE BEFORE AND AFTER CLIMBING FIXED NUMBER OF STAIRS.

So we have come to the end of our research study.
Overall,
Priscilla chin :
'Although its very tough and stressful, but i learn a lot of things such as using SPSS. I hope that this experience can help me better in my 3rd year final project.'

Atiqah:
'I must say it has been one stressful project that i have worked on. There are alot of problems we faced but somehow we managed to counter it. It has been great fun working with my group members.'

Ei Khaing Soe
'Although it's stressful project, I learnt something and I can say it's interesting and we had fun working on it. '

Adeline
'Its been a fun experience working with my mates. We get to learn together and play togther. It is stressful of course but we manage to handle it well and i guess our outcome is good. '

A special thanks to our teacher Miss Chia and all the people who participated in the study.lLast
but not least is those who helped us in analysing our data. Very much appreciated.

Thank you so much. Hope you enjoy viewing our blog!!♥

Upon review of our research question and that is, is there any relationship between blood pressure before and after climbing fixed numbers of stairs? So our question is asking for any relationship between two variables.

Blood pressure before climbing stairs = scale data.

Blood pressure after climbing stairs = scale data.

We took a look at the decision path in choosing our statistical test. Here's how

We chose Pearson's R to be our statistical test to analyse our results. We know that when analysing a correlation question, we need to consider 2 factors which is the DIRECTION (positive or negative correlation) and STRENGTH:

First thing first, we need fulfil 4 assumptions when suggesting Pearson's R as our test.

All observations must be independent of each other.

The dependent variable should be normally distributed at each value of the independent variable.

The dependent variable should have the same variablility at each value of the independent variable.

The relationship between the dependent and independent variables should be linear

So we have came up with a scatter plot to check for linearity and homogenous variance ( assumption 3 and 4)

This is our before and after systolic's scatter plot.

In considering the 2 factors, direction and strength,

Direction = positive correlation. (The scatter appears to follow a general positive linear trend)

Strength = 0.094.

So you can see that there is a positive direction but very weak strength.

This is our before and after diastolic's scatter plot.

In considering the 2 factors, direction and strength,
Direction = positive correlation. (The scatter appears to follow a general positive linear trend)
Strength = 0.131

So you can see that there is a positive direction but very weak strength.

Compute Pearson's correlation co efficient

Diastolic

Systolic

So we set our Alpha value as 0.10.

From the systolic symmetric measure, we know that our p value is 0.10.

P(0.10) less than or = to alpha (0.10)

From the diastolic symmetric measure,we know that our p value is 0.05

p(0.05)less than or = to alpha (0.10)

Therefore, we reject our null hypothesis.

Correct blood pressure measurements are essential to diagnosing and treating high blood pressure. Accordingly, a specific set of techniques and procedures have been developed which describe the proper method for obtaining the most accurate blood pressure readings possible. Because research has shown that medical professionals often do not completely follow these guidelines, it is important for the patient to be able to identify when proper protocol is not being followed.

Choose the Proper Cuff Size

One of the most important factors that can influence the accuracy of blood pressure readings is the size of the blood pressure cuff that is used.

The official guidelines specify the following cuff sizes:
· Arm circumference 22 to 26 cm, 'small adult' cuff, 12 x 22 cm
· Arm circumference 27 to 34 cm, 'adult' cuff: 16 x 30 cm
· Arm circumference 35 to 44 cm, 'large adult' cuff: 16 x 36 cm
· Arm circumference 45 to 52 cm, 'adult thigh' cuff; 16 x 42

Accurate Blood Pressure Readings Require Proper Positioning

Proper positioning is vital in obtaining accurate blood pressure readings.
In general, blood pressure should be measured while you are seated comfortably. The arm being used should be relaxed, uncovered, and supported at the level of the heart. Only the part of the arm where the blood pressure cuff is fastened needs to be at heart level, not the entire arm.

Multiple Blood Pressure Readings Should Be Taken

One blood pressure reading is not enough to get an accurate measurement. While the specifics of how many readings are necessary can change based on many factors, the essential need for multiple measurements does not.

We confirmed our validity and reliability last post. Now we need to deal with our ethnic issues.

Informed consent: VERBAL CONSENT

What did we include in our verbal consent. We mentioned

subjects to climb up the 68 stairs running.
We are NOT liable for any injuries cause.
After the experiment, a can of coca cola will be given to them as a appreciation.

We took some photos. We blurred some of it to ensure confidentiality.

There's 5 picture here. First top right corner, you can see one of our suject running. Next to it is a can of coca cola and the handphone to take the timing for subjects to run up. After finish climbing, we will take their blood pressure twice.

this is the chart that we are going to write in it.

Analysis is up next!

coming soon!

Before any data collection, we as a researcher must first test out the experiment to see if there is any harm to our subject. So we ran a pilot on 24th June 2008.

So this was where our pilot was held. A back view of the place.

We use this same instrument to measure our blood pressure and on the day itself.

One part of the stairs that we will be climbing.

Priscilla is running up the stairs.

After we make sure that our obtained pilot results are consistent and that there is no harm caused during the experiment. We carried on with our experiment the next day. This will be elaborated further on the next post. So see you guys soon!

We are from subgroup 2 of NR 0730

We have came up with a research topic to study on and here is our research topic.

STUDY OF RELATIONSHIP OF BLOOD PRESSURE

BEFORE AND AFTER CLIMBING UP FIXED NUMBERS
OF STAIRS

What is the purpose of the study you might ask?

It is to determine if there is any relationship between blood pressure before and after climbing
fixed numbers of stairs

Our research question:

Is there any relationship between blood pressure before and after climbing fixed numbers of
stairs?

Our variable:

Independent - blood pressure before. (scale)
Dependent - blood pressure after. (Scale)
Extraneous - Gender, age, individual with hypertansion/hypotension, time

Comceptualisation

Climbing uo fixed numbers of stairs: RUNNING up 68 steps without stopping
Blood Pressure : Generally refers to arterial pressure, i.e the pressure in the large arteries.

Operationalisation

Climbing up fixed numbers of stairs: Running up 68 steps without skipping any of it
Blood Pressure: Using 2 manual blood pressure sets and 2 stethoscopes.

We are targeting on 30 randomly chosen subject of any age and gender.

So with all these, our RESEARCH HYPOTHESIS is:

There is a positive relationship between blood presure before and after climbing fixed numbers
of stairs.

And our NULL HYPOTHESIS is:

There is no relationship between blood pressure before and after climbing fixed numbers of
stairs.

thats all for our introduction! stay tune for more!
