Quiz
Take the quiz to test your understanding of the key concepts covered in the chapter. Try testing yourself before you read the chapter to see where your strengths and weaknesses are, then test yourself again once you’ve read the chapter to see how well you’ve understood.
1. Match the definition to the correct research term:
Research term
- Non-probability sampling
- Inductive reasoning
- Bias
- Data saturation
- Iterative process
- Reflexivity
Definition
- The constant review of data until data analysis has been completed
- When the findings are distorted
- Development of a theory based on a study’s findings
- The researcher reflects upon the impact of their knowledge, experience and beliefs on the conduct of the research
- When data collection and analysis does not reveal any new findings and so the recruitment of further participants is unnecessary
- Participants are recruited because they have ongoing or prior experience of the phenomena the researcher is exploring
Answer:
- Non-probability sampling – participants are recruited because they have ongoing or prior experience of the phenomena the researcher is exploring
- Inductive reasoning – development of a theory based on a study’s findings
- Bias – when the findings are distorted
- Data saturation – when data collection and analysis does not reveal any new findings and so the recruitment of further participants is unnecessary
- Iterative process – the constant review of data until data analysis has been completed
- Reflexivity – the researcher reflects upon the impact of their knowledge, experience and beliefs on the conduct of the research
2. Identify which of the following characteristics apply to quantitative research and which apply to qualitative research:
-
Underpinning paradigm of positivism

-
Rigour determined by assessing validity and reliability
-
Aims to discover empirical evidence
-
Underpinning paradigm of interpretivism
-
Starts with an hypothesis or null hypothesis
-
Inductive reasoning
-
Uses fixed, structured designs
-
Nature of evidence objective
-
Aims to discover meanings
-
Involves large, representative samples
-
