    1. 1. Research Methods HS 2196 Sub- group 1
    2. 2. Objectives Identify the research problem and research topic in this presentation Identify research and null hypothesis List the types of variables used in the research Discuss about the conceptualization and operationalization of variables Identify the type of sampling used Discuss about our research proposal and the ethical considerations
    3. 3. Research problem
    4. 4. Research Topic
    5. 5. Types of Variables
    6. 6. Hypothesis Null Research Hypothesis (H0) Hypothesis(H1)There is no significant There is significantrelationship between relationship betweenconsumption of coffee consumption of coffeeand blood pressure and blood pressure
    7. 7. ConceptualizationConsumption of coffee—consume coffee orallyBlood pressure—pressure exerted by the blood on thearterial walls as the heart pumps blood into the aorta. (Brooker, 2005)
    8. 8. OperationalizationConsumption of coffee— drink 150mls coffee(100mgcaffeine) within 10 minutesBlood pressure— measured using a BP set 30 and 60minutes after drinking coffee It is generally recorded indirectly in the brachial artery using an electronic device or stethoscope and sphygmomanometer and recorded in millimetres of mercury pressure (mmHg) There are two readings: systolic reading and diastolic reading. (Brooker, 2005)
    9. 9. Literature review (Nurminen, Niittynen, Korpela & Vapaatalo, 1999)
    10. 10. Literature review (Nurminen, Niittynen, Korpela & Vapaatalo,1999)
    11. 11. Literature review (James, 2004)
    12. 12. Literature reviewCaffeine tolerance diminishes the acute effect of caffeine on blood pressure, and hypertensive individuals are more susceptible to blood pressure changes.
    13. 13. Literature review (Riken, Rongen & Smits, 2009)
    14. 14. Literature review (Buscemi et al., 2010)
    15. 15. SamplingTarget population
    16. 16. Sampling Using cluster samplingStep 1:clusters are chosen Year 1 Group A—1 Year 1 Group B—2 Year 1 Group C—3 Year 1 Group D—4 Year 2 Group A—5 ……12 groups in total Step 2:choose 10 individuals using simple random sampling from each group (cluster) 120 Nursing students to participate in the experiment
    17. 17. Measuring instruments2 electronic blood pressure sets of same brand will be used
    18. 18. Methods of data-collection Age Blood Pressure
    19. 19. ExperimentControl Group Design O1 X O2 O3 R O1 O2 O3
    20. 20. Experiment Cluster (one lecture group of nursing student)Controlled Group Experimental Group (will be given (will be given one cup nothing) of coffee)
    21. 21. 1 2
    22. 22. Experiment Start Blood pressure measuring & record Control group Experimental group Drink nothing Drink a cup of coffee End listen light musicfor 30 minutes Blood pressure Blood pressure measuring and record measuring and record listen light music for another30 minutes

    25. 25. Data analyseData were entered and analyzed withSPSS (Version18): Compare result measured after 30 minutes and 60 minutes Compare result between controlled group and experimental group Male & female
    26. 26. Feasibility• Confirm the lecture time with one student of the selected group• Ensure there is no any lecture or tutorial after the study for the participators• Ensure that the participators are not allergic to caffeine
    27. 27. Research ethicsDistribute and explain the consent form-Introduce ourselves-Explain the purpose, procedure of our study-Identify for any allergy-Identify the right to refuse to participate or towithdraw from study without penalty-Offer to answer all questions-Confidentiality is assured(age)
    28. 28. ConclusionA simple researchproposal to do aresearch on correlationbetweenconsumption of coffeeand Blood pressure Take noted & apply in clinical area
