Finding, Collecting and Organising Data Flashcards
What is the difference between primary data and secondary data?
Primary: first-hand data gathered by researcher themself
Secondary: data collected by someone else earlier
How are the hypotheses for quantitative research structured?
- Questions ask about the relationship between the variables that the investigator wants to know.
- Widely used in social science research and in survey studies in particular.
What are quantitative assumptions?
- Predictions made by the researcher about the expected relationship between variables.
- Observed estimates of population values based on data obtained from surveys
What is a ‘pilot study’?
- Preliminary smaller-scale study that helps researchers to test and develop research methodologies before the actual major study.
What is sampling used for?
- To have valid results from anu research study since it is practically impossible to study an entire population
Name the two types of sampling:
- Probability sampling
- Non-probability sampling
Define the three types of probability sampling:
- Stratified sampling:
- Splitting population into different categories and then choosing units at random from different categories - Cluster sampling:
- Researcher divides population into groups called “clusters”. A random sample of clusters will then be selected from the population.
- Researcher provides a summary of the data from the clusters sampled. - Simple random sampling:
- Each item in the population has an equal chance and probability of being selected in the survey (important in quantitative data analysis)
Name and define the three types of non-probability:
- Deliberate sampling:
- Researcher chooses sample based on their knowledge of the study and the population.
- Participants are chosen based on intent of the sample (used in qualitative analysis. - Snowball sampling:
- Research participants recruit other participants for a test or study.
- Used where prospective participants are difficult to locate. - Convenience sampling:
- Individuals are sampled purely because they are convenient sources of data for researchers (also referred to as ‘accidental samples’)
What is deliberate sampling also known as?
- Purposive sampling
What is convenience sampling also known as?
- Accidental samples
What does ethics refer to in data analysis?
Characterised as the principles of conduct that govern a person or a community and the moral duty and obligations to which we must comply.
What entails good research practice?
- Researcher thinking through all potential risks and ethical concerns before embarking on any data collection or analysis.
What are good ethics?
- Researchers not breaching the privacy of the participants.
