Three assumptions that differentiate qualitative and quantitative studies Epistemology
▪ Qualitative researchers believe there are multiple realities represented by the participants’ perspectives
▪ Quantitative researchers believe a single, objective reality exists
Copyright © Allyn & Bacon 2008
Three assumptions (continued) Context
▪ Qualitative researchers believe context is critical to understanding the phenomena being studied
▪ Quantitative researchers do not believe context is an important factor
Researcher bias▪ Qualitative researchers believe the researcher’s biases and
perspectives must be understood to interpret the results▪ Quantitative researchers believe researcher bias is
controlled through the control of internal validity threats
Copyright © Allyn & Bacon 2008
Characteristics of qualitative research Natural settings - field research
▪ Behavior is studied as it occurs naturally▪ Beliefs related to a natural setting
▪ Behavior is understood bests as it occurs without external constraints or control
▪ The situational context is very important to understanding behavior
Copyright © Allyn & Bacon 2008
Characteristics of qualitative research Data collection
▪ Data is collected directly from the source▪ Observations▪ Interviews▪ Document analysis
Rich narrative descriptions Process orientation
▪ How and why behaviors occurCopyright © Allyn & Bacon 2008
Characteristics of qualitative research Inductive data analysis Participant perspectives define what
is “real” Emerging research design
▪ The design plans change as data is collected, analyzed, and understood
Copyright © Allyn & Bacon 2008
An ethnography is an in-depth description and interpretation of cultural patterns and meanings within a culture or social group Culture - shared patterns of beliefs,
normative expectations, behaviors, and meanings
Shared, not individualistic
Copyright © Allyn & Bacon 2008
Problem statements Foreshadowed problem - a general
framework for beginning a qualitative study
Specific question - a question(s) that emerges from the interactive relationship between the problem and data▪ Often found embedded in the data analysis▪ Changing nature of questions often
necessitates changes in the design (i.e., an emergent design)
Copyright © Allyn & Bacon 2008
Identifying and entering the research site Access to all parts of the site
▪ Participants▪ Documents▪ Physical location
Rapport - need to be “integrated” within the site to gain the trust of the participants
Often site entry takes a long timeCopyright © Allyn & Bacon 2008
Selecting participants Use of purposeful sampling strategies to
select “information rich” participants Purposeful sampling strategies
▪ Maximum variation - selecting individuals or cases to represent extremes▪ Very positive or very negative attitudes▪ Highest and lowest achieving students)
▪ Snowball (i.e., network) - initially selected participants recommend others for involvement
Copyright © Allyn & Bacon 2008
Purposeful sampling strategies▪ Sampling by case - selecting individuals or
cases for their unique characteristics▪ Extreme▪ Typical▪ Unique▪ Reputation
▪ Key informant - selecting an individual(s) particularly knowledgeable about the setting and or topic
▪ Comprehensive - selecting all relevant individuals or cases

Three primary methods for obtaining data Observation Interview Document analysis
Copyright © Allyn & Bacon 2008
Observation Unstructured in nature Comprehensive - continuous and total over an extended
period of time Participant-observer role of the researcher
▪ Continuum between complete participant and complete observer▪ Passive participant▪ Moderate participant▪ Active participant▪ Complete participant
▪ Rare for an ethnographer to be a complete participant
Copyright © Allyn & Bacon 2008
Observation (continued) Use of field notes to record observations
▪ Two types of information▪ Descriptions of what occurred▪ Reflections of what the descriptions mean (i.e.,
speculations, emerging themes, patterns, problems)
▪ Accuracy▪ Extensive nature of notes
Copyright © Allyn & Bacon 2008
Interviews Unstructured in nature Begins with a general idea of what needs to be asked
and moves to specific questions based on what the respondent says
Types of interviews▪ Key informant▪ Life history▪ Focus group
Tape recording and transcribing interviews afford the opportunity to study the data carefully
Copyright © Allyn & Bacon 2008
Document analysis Written records
▪ Print (e.g., minutes from meetings, reports, yearbooks, articles, diaries)
▪ Non-print (e.g., recordings, videotapes, pictures) Types of sources
▪ Primary - original work▪ Secondary - secondhand interpretations of original work
Commonly used to verify other observations or interview data
Copyright © Allyn & Bacon 2008
Data analysis and Interpretation Observations, interviews, and document
analyses result in large quantities of narrative data
Analysis includes critically examining, summarizing, and synthesizing the data
Copyright © Allyn & Bacon 2008
Three stages of analysis Coding
▪ Organizing the data into reasonable, meaningful units that are coded with words or very short phrases that signify a category▪ Emic categories - information provided by the
participants in their own language and organizational units
▪ Etic categories - the researcher’s interpretation of emic data
▪ Use of major codes and sub-codes is common
Copyright © Allyn & Bacon 2008
Summarizing the coded data▪ Examining all similarly coded data and
summarizing it with a sentence or two that reflects its essence
▪ Computerized sorting of data is common and effective
Pattern seeking and synthesizing▪ Synthesizing identifies the relationships among
the categories and patterns that suggest generalization
▪ The researcher interprets findings inductively, synthesizes the information, and draws inferences
Copyright © Allyn & Bacon 2008
Pattern seeking (continued)▪ Developing patterns
▪ Begins with the researcher’s informed hunches and ideas
▪ Tentative patterns are identified and additional data collected to determine if they are consistent with those patterns
▪ Characterized by enlarging, combining, subsuming, and creating new categories that make sense
Copyright © Allyn & Bacon 2008
In-depth analysis of one or more events, settings, programs, groups, or other “bounded systems” Focus on one entity Defined by time and place Concern with the limited generalizability
of the findings
Copyright © Allyn & Bacon 2008
Types of case studies Historical organizational - focus on the
development of an organization over time
Observational - study of a single entity using participant observation
Life history (i.e., oral history) - a first-person narrative completed with one person
Copyright © Allyn & Bacon 2008
Types of case studies (continued) Situation analysis - a study of a specific
event from multiple perspective Multi-case - a study of several different
independent entities Multi-site - a study of many sites and
participants the main purpose of which is to develop theory
Copyright © Allyn & Bacon 2008
Research problem statement Focus on in-depth description and
understanding Use of a single major question and
several sub-questions Emerging nature of the problems
Copyright © Allyn & Bacon 2008
Identifying and entering the research site
Selecting participants Participants are usually identified as a
part of the site of the study (e.g., a classroom, teachers in a specific department, etc.)
Internal sampling - selecting specific participants, times, and documents within a site
Obtaining dataCopyright © Allyn & Bacon 2008
Data analysis Same procedures as in ethnographic data analysis Four types of data analysis
▪ Categorical aggregation - researcher codes data and collects instances from which meanings will emerge
▪ Direct interpretation - use of a single example to illustrate meaning
▪ Drawing patterns - examines the correspondence between two or more categories or codes
▪ Naturalistic generalization - suggestions as to what others can take from the research and apply to other situations
Copyright © Allyn & Bacon 2008
A phenomenological study describes and interprets the experiences of participants to understand their perspectives
Based on the belief that there are multiple ways of interpreting the same experience and the meaning of that experience is what constitutes reality
Copyright © Allyn & Bacon 2008
Research problem Focused on what is essential for the
meaning of the event, episode, or interaction
Selecting participants▪ Participants are selected because they have
lived or are living the experience being investigated
▪ Participants will share their experiences▪ Participants can articulate their feelings
Copyright © Allyn & Bacon 2008
Obtaining data - in-depth, semi-structured, or unstructured interviews
Data analysis Concerns that the analysis reflects the shared meanings
and consciousness of the participants Five step process
▪ A initial description of the researchers experience with the phenomena
▪ A statement how the participant’s experience with the phenomena are identified in the interview
Copyright © Allyn & Bacon 2008
Five step process (continued)▪ The creation of meaningful units form the
statements using participant’s verbatim language to illustrate the units
▪ Separation of what was experienced from how it was experienced
▪ The construction on an overall description of the experience
Copyright © Allyn & Bacon 2008
A grounded theory study discovers or generates a theory A theory is a set of propositions that pertain to a specific
experience, situation, or setting The contextual sensitivity of the theory is the basis for
suggesting the theory is “grounded” in the field data Research problems - broad general questions
that focus on what happened to people, why they believed it happened, and what it means to them
Copyright © Allyn & Bacon 2008
Selecting participantsObtaining data - in-depth
unstructured interviewsData analysis
Constant comparison - information from interviews is compared to emerging themes as a part of a more encompassing theory
Copyright © Allyn & Bacon 2008
Data analysis (continued) Four step process
▪ Form initial categories with subcategories and descriptions of extreme possibilities on a continuum
▪ Create a coding paradigm in which central tenets are described with causal conditions, resultant actions, conceptual conditions and consequences
▪ Write a story that integrates selective codes that have been established and presents conditional propositions and hypotheses
▪ Explicate the theory
Copyright © Allyn & Bacon 2008
Credibility is the extent to which the data, data analysis, and conclusions are believable and trustworthy
Four technical issues Triangulation - the comparison of results obtained from
different data collection methods (i.e., interviews, observations, and document analyses all lead to a similar conclusion)
Reliability - the extent to which what is recorded as data is what actually occurred in the setting (i.e., the accuracy of observations)
Copyright © Allyn & Bacon 2008
Four technical issues (continued) Internal validity - the match between the researcher’s
categories and interpretations and reality▪ Threats related to observer effects are of paramount concern▪ Other threats include maturation, history, selection, attrition,
and subject effects External validity – generalizability
▪ Translatability and comparability are terms used to indicate the extent to which the results can be used by other researchers in other settings
▪ Generally weak in qualitative research
Copyright © Allyn & Bacon 2008
Techniques to enhance credibility Triangulation Prolonged and persistent field work Copious field notes Low inference descriptors Mechanically recorded data Member checking Verbatim accounts Researcher’s role as participant observer
Copyright © Allyn & Bacon 2008
The researcher’s background, interests, and potential bias should be clear
Conceptual and/or theoretical frameworks for the study should be clear
The method for selecting participants should be clear
The level of the researcher’s involvement in the setting should be indicated
The researcher should be trained in data collection procedures
Copyright © Allyn & Bacon 2008
Credibility of the research should be addressed
Descriptive data should be separated from the interpretations of the data
The researcher should use multiple methods of data collection
The duration of the study must be long enough
