Quantitive Data Collation

Quantitive Data Collation

1. Study design and research question influences data collation

   • Records
     • i.e Health data from existing sources collected on asthma and maternal smoking.
       • collected using a standardised case reporting form.
         • Health records (usually hospital) are commonly used in health research.
   • Case series
     • data on physiological measures (i.e. related to an organ or body functions) is often collected
   • Questionnaires
     • administered by interviewers face to face, or by phone
       • one study a self-administered questionnaire was used.
         • most common methods of data collection

2. physiological data

   • can be collected from primary sources (i.e. directly by conducting tests on a patient, or developing a questionnaire to extract the data),
     • secondary sources (i.e. obtaining data from records).
     • -Xrays, MRI scans, electrocardiograms, respiratory function tests, blood pressure, and many types of laboratory tests (e.g. blood, cholesterol, glucose test).
     • Videotape observations
       • example to obtain data on infant pain during immunisation
       • not a commonly used method in quantitative research studies but can be used to great effect if conducted correctly.

3. Physiological/Clincal data measures

   • Health research often focuses on some aspect of a person's health status.
     • result the researchers may collect physiological data from a variety of sources.
       • i.e new medication which reduces blood pressure.
         • measure BP
   • not always practical to collect to reasons bc cost or the lack of appropriately trained staff.
     • so we need participants to report these variables using a survey.
       • survey in which they are asked to report their height and weight so we can then calculate BMI.
