Quantitative research focuses on the left brain - objective, comfortable with logic, numbers, and unchanging static data and detailed, convergent reasoning rather than divergent reasoning. Qualitative research deals with the right brain - the hemisphere accountable for processing data as words, emotions, feelings, emotions, colour, and music.

QUALITATIVE & QUANTITATIVERESEARCHEditor: Stephen Murray
KEEP IN MIND THAT …• Qualitative researchgenerally deals in words,images and the subjective• Quantitative researchgenerally deals innumbers, logic and theobjective
QUALITATIVE RESEARCH• Research used in range of activitiesfrom exploratory designs to meansof completing explanations• Qualitative research assumes thatpeople have meaningfulactions or experiencesthat can be interpretedAgendaDefinition When touse?TypesFOCUS GROUPSIN DEPTHINTERVIEWPROJECTIVE TECH.Pros&Cons

QUALITATIVE RESEARCH• Identification of a given question; opportunityor information requirements• Interest in obtaining insights formotivational /social (group) or emotional andattitudinal (individual) factors• In IR: primary data of events or personalitiessupporting explanations and argument• (Cf. In marketing: for new product launch, new servicedevelopment or repositioning current product

QUALITATIVE RESEARCH DESIGNQualitative Research: • Examples• Case studies on effect of vocational training in Papua • Ethnographic studies on indigenous populations in Oaxaca, Mexico Qualitative Research Types:• Case studies • Developmental research • Historical research • Ethnograph studies • Case Studies:• Purpose: to do an in depth study• In brief: Background, current status and/or environmental factors that interact for each group (individual, institution or community)
• Characteristics of Case Studies:• It gives very detailed information about individuals / group / community• It may give a detailed explanation of a complete life cycle or part of it• Number of cases studied may be small but the number of variables studied are usually more in-depth (e.g. if compared to a survey)• Developmental Research: • Conducted to research on the development of individuals / group / institution / community • TWO TYPES: Cross-sectional and Longitudinal • Historical Research:• Used to gain information on an event, development and/or previous educational experience• Process may involve studying previous situation, checking on current situation, and to predict if the same situation will occur again • Conclusion on previous event is done based on collected facts and evidences to answer why and how the event and repercussions occurred• Useful to solve questions that involve sensitive issues • Important for systematically & objectively collecting and defining facts and evidences
• Procedure for Historical Research:• Define the problem • Specify source of evidence • Collect evidence / reference materials • Primary source / original (observation or witnesses of events or authentic objects – e.g. artifacts, speech text, records etc.) • Secondary source (materials or information collected from primary sources – e.g. paintings, films, news reports, documents • Critique of evidences – External critique: confirming if collected sources are genuine and reliable (authenticity of paintings, signatures, chemical analysis etc.) – Internal critique: conducted after authenticity of source of information is confirmed – involves evaluation of collected evidences– is it important? Required? • Able to explain the researched phenomenon? • Prepare the report • Ethnographic Research:• In-depth study of natural behaviours in a culture or social group • Purpose – to understand relationships between behaviour and culture – Example: In education – to understand schooling process (e.g., immigrant children) Involves widespread observations (participant & nonparticipant) • Here often starts research without hypothesis – hypothesis is developed in the process of observations, and the researcher explores and test his hypothesis
QUALITATIVE RESEARCHIN-DEPTH INTERVIEWCharacteristics:• A well trained interviewer+interviewee• Interviewee is exposed to set of probing questions• Usually face to face• Interviewer encourages the interviewee to talk moreGoal:• To collect as much as memory, attitudinal and behavioral data from the subjectAgendaDefinition When touse?TypesFOCUS GROUPSIN DEPTHINTERVIEWPROJECTIVE TECH.Pros&Cons

QUALITATIVE RESEARCH PROJECTIVE TECHNIQUEDefinition:*• These are unstructured prompts or stimulus that encourage the respondent to project their underlying motivations, beliefs, attitudes, or feelings onto an ambiguous situation • They are all indirect techniques that attempt to disguise the purpose of the research AgendaDefinition When touse?TypesFOCUS GROUPSIN DEPTHINTERVIEWPROJECTIVE TECH.Pros&Cons*Source: http://en.wikipedia.org/wiki/Qualitative_marketing_research

SUMMARY• Qualitative methods focus on generating exploratoryinitial/progressive insights into questions and problems• Depth probing of hidden attitudes, feelings or behaviour• Focus Groups• In depth Interviews• Projective Techniques
SUMMARY• Quantitative Research is interested in using formalised,standard structured questioning, whereby response optionsare pre-determined• Usually to be administered to significantly large numbers ofpeople.Descriptive Causal(Surveys) (Experimentation)
