Quantitive Data
Collation
- 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
- 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.
- 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.
