Induction, deduction, abduction
Types of sampling in qualitative research
Non probability sampling techniques
Conducting an interview
Analysis of qualitative
Ethnography
Induction, deduction and abduction
- Inductive
The relationship between data and
- Abductive
generalization in scientific work
- Deductive
• Inductive research: Research that begins with the data and then generalizes or
produces theoretical generalization from the data
• Abductive research: Research that attempts to build theory from “surprises” in
empirical data (first collect data > theory)
• Deductive research: Research that takes a “top-down” approach where the
theory or hypothesis drives the data collection strategy and analysis (theory >
data)
Grounded theory (inductive nature): is
NOT a theory but rather a method of
analyzing qualitative data inductively in
order to generate theory

Types of sampling: In Grounded Theory
1. Purposive sampling A sampling strategy in which cases are
(or theoretical sampling) deliberately selected on the basis of
features that distinguish them from other
cases
2. Sequential sampling Researchers select interview cases as the
study proceeds, with the goal of building
on emerging findings
• Saturation: when new materials (interviews, observations, survey responses), fail
to yield new insights and simply reinforce what the researcher already knows.
Approaches: deductive, inductive and extended case
• Deductive approach: Compare data with the results predicted by existing
theories
• Inductive approach: Focusing on unexpected or anomalous findings that
need new explanations
• Extended case study approach: An approach to theory in qualitative
research which the researcher starts with an established theory and
chooses a field site or case to improve upon or modify the existing theory
Non Probability Sampling Techniques
• Convenience sampling: uses samples that are chosen merely on the basis of
who is easy to reach
• Purpose sampling: study only certain kinds of people, and recruit only those
particular participants
• Snowball sampling sampling: participants are asked to recommend a few
acquaintances for the study (it is unrepresentative)
• Quota sampling: researcher identifies subsets of the population of interest and
then sets a target number for each category in the sample
Quota and Stratified Random Sampling
• Quota: participants are selected non randomly (perhaps through convenience or
purposive sampling)
