Core 1 - Research Methodology Flashcards
What does conducting research allow us to do?
→ Advance Knowledge
→ Increase Understanding
→ Educate Others
→ Inform Practice
What is a Research Question?
Is an answerable inquiry into a specific concern or issue. It is the initial step in a research project.
eg. What happens to an adolescent females physical activity levels in high school? (Open)
eg. Do the physical activity levels of adolescent females increase or decrease in high school? (Closed)
What is a Hypothesis?
A supposition or proposed explanation made on the basis of limited evidence as a starting point for further investigation.
eg. An adolescent females physical activity levels decrease when they reach high school.
eg. Adolescent females are reaching the Australian Guidelines for physical activity.
Define Sample Methods.
The methods used to choose the sample group
What are the Different Types of Sample Methods?
→ Random Sampling → Systematic Sampling → Cluster Sampling → Convenience Sampling → Stratified Sampling
Define Random Sampling
Selecting people so everyone has an equal chance of being selected.
Define Systematic Sampling
Choosing one number at random and then every nth unit after this random start.
Define Cluster Sampling
Dividing a population into clusters and random selection is made within these clusters.
Define Convenience Sampling
When a researcher selects people because they are easily located. These results have the lowest credibility.
Define Stratified Sampling
A process in which a population is divided into strata groups and the researcher can ensure that there is a more balanced reputation in each of the strata groups and that the groups can be compared with each other in similar proportions to the whole population.
Define Sample Groups.
The groups chosen as the sample for the study to be under taken.
Define Sample Size
The number of people who will participate in the research methods
What are the Types of Data?
→ Primary
→ Secondary
→ Quantitative
→ Qualitative
Define Primary Data
Collecting ‘new’ data, that is, data that does not exist before the research is undertaken.
eg. the researcher might use interviews and questionnaires in order to collect data from various people and the data has not been previously collected and interpreted.
Define Secondary Data
Collecting data from existing research.
eg. The researcher might collect data and information from a number of secondary sources such as books and journals. He or she will then collate the collected data and interpret it by looking for recurring arguments, themes and conclusions.
Define Quantitative Data
Measuring or collecting facts in the form of numbers and drawing relationships between facts through statistical analysis and experimentation.
eg. Show percentages or ratios, Compare numbers in text, Visually represent the amounts or levels of something in tables or graphs.
Define Qualitative Data
Collecting non-numerical data to provide an explanation for something.
eg. Compare people’s opinions or ideas or Present arguments for and against something
What are the Sources of Data?
→ Individuals
→ Groups
→ Print
→ Digital
How are Individuals a Source of Data?
Individuals/people can be sources of primary data, which can be collected by means of surveys, case studies or observations.
eg.
→ People in a particular context, such as a workplace, school, home or sporting event
→ A range of people from all walks of life
→ People involved in a particular situation, such as a celebration, a community event, conflict, parenting or caring.
How are Groups a Source of Data?
Organisations and other groups can be sources of primary data, which can be collected by means of surveys, case studies and observations. They can also be sources of secondary data, which can be collected by means of literature reviews.
eg.
→ Staff of a particular organisation, such as nurses or childcare workers
→ Experts in a particular field, such as marine biologists or university lecturers
→ Particular groups within the community, such as families, young people or elderly people
→ Pamphlets or brochures produced by an organisation
→ Data previously collected by an organisation, such as by the Australian Bureau of Statistics or the Australian Institute of Health and Welfare.
How is Print a Source of Data?
Print sources can be used to collect secondary data by means of literature reviews.
eg. → Newspaper articles → Books, including biographies and autobiographies → Journals → Magazines → Encyclopaedias → Research reports → Annual reports → Pamphlets and brochures.
How is Digital a Source of Data?
Electronic sources can be used to collect secondary data in the form of electronic publications and case studies. They can also be used to collect primary data through observation.
eg. → Websites → Television programs → Videos → DVDs → CD-ROMs → Radio programs.
Define Reliability.
Consistency of research findings
Define Validity.
The legitimacy of findings, refers to nature of entire research process and justification of results
