Research Methodology
Quasi experiments:
"natural experiments" entailing manipulation of social setting.
Steps for coding
1) read transcript 2) generate codes 3) review codes 4) generate theorical ideas
Qualitive research process
1) research questions 2) choose methodology 3) collect data 4) interpretation of data 5) conceptual and theorical work 6) prepapre your report/ findings
Research process
1)Analysis: identify and clarify research question 2) Planning: research proposal, research design 3)implementation: Data collection and analysis,and reporting
narrative interview
A kind of qualitative interview in which the researcher is interested in the participant's story or stories about some experience or phenomenon.
Research method
A systematic plan for doing research. It can be associated with different kinds of research designs, the technique for collecting data.
Validity
Accuracy, integrity of conclusions
Strategies of qualitative data analysis
Analytic induction, grounded theory and coding
Cross sectional study
Data are observed, measured, and collected at one point in time.
Descriptive Studies
Description of relatively well known circumstance and measuring of the frequency of occurrence. Studies that collect detailed information about specific situations.
Evaluative Studies
Determination of effectiveness of measures.
Focused interview: Specificity
Determine the impact of an event for interviewees. Encourage retrospective inspection.
Exploratory Studies
Discovery, development of hypotheses. Investigation of a new phenomenon. Tendency to use on qualitative methods.
Basic type of research design
Exploratory, descriptive, explanatory and evaluative
Case study designs:typology Stake (1995)
Intrinsic, instrumental, multiple/collective
Types of coding
Open, Axial, selective
Inductive theory
Proceeds from concrete observations from which general conclusions are inferred through a process of reasoning. researches infer the implications of his findings in the theory.
Difference between qualitative and quantitative
Qualitative is data that can be observed but not measured and Quantitive is information that can be counted or expressed numerically
Theoretical sampling
Selecting sample members based on earlier interview that suggest that particular types of participants will help researchers better understand the research topic
Purposive Sampling
Subjects are deliberately selected based on predefined criteria chosen by the investigators. Select interviewees who are relevant to research questions.
Explanatory Studies
Test the hypotheses, explains associations and causal relationships.
ecological validity
The extent to which a study is realistic or representative of real life. applicable to people's everyday and natural settings.
Reliability
The extent to which a test yields consistent results.
Middle range theories
Theories that address a specific phenomenon and reflect practice. Explain a portion of human experience. E.g Decision making
Disadvantages of Qualitative research
When collect data about what your select group of participants feel or think, or how they behave. You can't necessarily use this data to make assumptions beyond this specific group of participants. It is not a research method that conveniently allows for the collection of statistical data. However this is only a disadvantage if your research question also requires statistical data. Adopting a mixed methods approach is one way of overcoming this problem.
Ontological
a branch of philosophy dealing with the meaning of being or the meaning of life
Expert interview
a discussion with someone knowledgeable about the problem or its possible solutions
A research design is
a plan and structure of investigation so conceived as to obtain answers to research questions.
Respondent validation
a process where a researcher provides the people on whom he conducted a research with an account of his findings. The aim is to seek corroboration
focus groups
a qualitative method that involves unstructured group interviews in which the focus group leader actively encourages discussion among participants on the topics of interest
Experiment
a research design that rules out alternative explanations of findings deriving from it.
content analysis
a research method in which observers systematically analyze media subject matter
Interviews
a research tool in which the investigator asks the participant questions
Grand theory
a theory designed to describe and explain all aspects of a given phenomenon. Indicate to researchers how they might guide or influence researches.
narrative analysis
a type of qualitative approach that focuses on the story as the object of the inquiry
grounded theory is well suited to
a) capture complexity b) linking with practice c) facilitate theoretical work in substantive areas that haven been not well research d) put life into well established fields
Characteristics of Quantitative
a) it is deductive, testing a theory b) natural science model, in particular positivism c) objetivism: The belief that certain things exist independently of human knowledge or perception of them. d) fixed procedures, narrow and precise e) focus on number measuring
Characteristics of Qualitative:
a) it is inductive, generation of theory b) Interpretativism: aim to construct or obtain in the practice c) constructivism: emphasis on the ways that people create meaning of the world through a series of individual constructs d) focus on words and pictures. e) flexible procedures
Tools of grounded theory
a) theoretical sampling b) coding c)theoretical saturation, d) constant comparison
elements of problem centered interview
a)qualitative method b) biogrphical method c) case analysis and d)group discussion
Focused interview
aim is to provide basis for interpreting statistically findings on the impact of media in mass communication
Open coding
applied in various degrees of detail. text is coded line by line. develop categories of information.
Focused interview:Non direction
are unstructured questions
multiple/collective case
can require extensive resources and time. it has rich theorical framework
intrinsic case
case-focused study
Research questions should be
clear, researchable, connect with established theory and research, have potential to make contribution to knowledge and should be neither too broad or too narrow.
Triangulation
combination of different methods to investigate a social phenomena
Evaluation research:
concerned with the evaluation of occurrences as organizational programmes or interventions
Selective coding
continues the axial coding to a higher level, focus on core concepts or core variables.
4 types of triangulation
data, researcher, theory, methodological
Qualitative and Quantitative research constitute
different approaches to social investigation and carry with them important epistemological and ontological considerations
Focused interview: depth and personal context
ensure emotional responses in the interview go beyond simple assessments. like : pleasant" .
Coding
entails reviewing transcripts and/or field noted that seen to be potential interest of study.
Kinds of Qualitive research methodology
ethnography, phenomenology, grounded theory, case study research
external validity
extent to which we can generalize findings to real-world settings
objetivity
free of bias.
measurement validity
how well an empirical indicator and the conceptual definition of the construct that the indicator is supposed to measure "fit" together
Qualitative methods includes
interviews, focus groups, biographical methods, participatory monitoring and content analyses
theory triangulation
looking at data through different theoretical perspectives
Types of validity
measurement, internal, external and ecological
Cognitive mapping
mental representation of the layout of one's environment
researcher triangulation
multiple researchers are used to collect and analyze data.
Qualitative interview types
narrative, problem-centered, expert, and focus groups
Epistemological
philosophical study of how we acquire knowledge
Problem centered interviews has 3 central criteria
problem centering, object orientation and process orientation
Axial coding
process of relating subcategories to a category. interconnecting information
Deductive theory
represents the most common view of the nature of the relationship between theory and research. The researcher on the basis of what he knows on a domain deduces a hypothesis that must be subject to empirical scrutinity.
Key elements of research design
sample selection, sample size, data collection, instrumentation, procedures, justification of method use, ethical requirements
Focused interview: range
securing that all aspects and topics relevant to the research questions are covered
using document as data
selecting, classifying and analyzing documents to conduct research.

strategy in which the same individuals are studied over a period of time, usually several years
Quantitative methods includes
surveys, experiments, statistical analyses of data
internal validity
the characteristic of an experiment that allows one to draw accurate inferences about the causal relationship between an independent and dependent variable
semi standardize interview
the relations formulated in these questions serve the purpose of making interviewees' implicit knowledge more explicit. The interview guide mentions several topical areas, introduced by an open question and ended by confrotational question.
methodological triangulation
the use of multiple research methods to achieve a more complete and accurate understanding
Options to quantify a qualitive research
thematic analysis, quasi qualifications, limited qualifications
instrumental case
theme-based study
problem centered interviews aim is
to focusing the interviewee's view of the problem around which the interview is centered.
Combining quantitative and qualitative research mixed methods
triangulation, facilitation (one approach aides the other), complementarity (different aspects are addressed with different methods
Alternative criteria for evaluation of research
trustworthiness(credibility, transferability, dependability and confirmability) and relevance(importance and contribution)
analytic induction
universal explanations of pehnomena by pursuing the collection of data until no cases inconsistent with hypotheses are found. Reasoning from empirical observations towards the creation of theories
A conceptual framework is
used in research to outline possible courses of action or to present a preferred approach to an idea or thought
snowball sampling
useful when there is no sampling frame. Recruitment of participants based on referrals from other participants
data triangulation
using a variety of data sources in one study
Replicability
whether a study can be repeated to produce similar findings or not
