    Learning Objectives

    This session seeks to discuss the different approaches

    to qualitative and quantitative research.

    By the end of the session, students will be able to

    understand and explain methods including case

    study, ethnography, content analysis, survey, and

    action research.

    Students will also learn about the different methods

    for collecting data in research. These methods

    include interviews and focus group discussion.

    DIFFERENCE BETWEEN

    QUALITATIVE & QUANTITATIVE

  • Research Methods Dr Richard Boateng [richard@pearlrichards.org] Photo Illustrations from Getty Images www.gettyimages.com 6

    Quantitative research emphasizes

    1. Starting with specific hypotheses or questions

    derived from theory/previous research

    2. Selecting a sample representative of the

    population

    3. Using objective instruments (e.g. fixed choice

    questionnaires, attitude scales, etc.)

    4. Presenting results using statistics and making

    inferences to the population.

    5. Distance between researcher and subjects

    and emphasis on following the research plan

    Qualitative research emphasizes 1. Starting with general research problems and not

    formulating hypotheses (hypotheses may emerge from the

    data analysis).

    2. Selecting a small, purposive sample (not random) which may

    or may not be representative of the larger population.

    3. Using relatively unstructured instruments (e.g. interviews,

    observations, etc.) and intense data collection (e.g. over

    extended periods of time).

    4. Presenting results mainly or exclusively in words, MORE

    ABOUT EXPLANATION, and de-emphasizing generalizations

    to the population

    5. Researcher awareness of their own orientations, biases or

    experiences and personal interaction in the context with an

    emphasis on flexibility in the research.

    Qualitative Research

    The qualitative research method involves the use of

    qualitative data, such as interviews, documents and

    observation, in order to understand and explain a social

    phenomenon.

    Qualitative research focuses on interpretation of

    phenomena in their natural settings to make sense in

    terms of the meanings people bring to these settings

    (Denzin and Lincoln 1994) .

    Types of Qualitative Research

    Case Study

    Case study research is a qualitative approach in

    which the investigator explores a bounded system (a

    case) or multiple bounded systems (cases) over

    time,

    through detailed, in-depth data collection involving

    multiple sources of information (e.g., observations,

    interviews, audiovisual material, and documents and

    reports), and reports a case description and case-

    based themes.

    Case Study

    Case study is a method used in both qualitative and quantitative

    research methodologies. Yin (1994) suggested that case studies are

    empirical investigation of phenomena within their environmental

    context, where the relationship between the phenomena and the

    environment is not clear.

    Therefore, a case is examined to understand an issue or provide

    input to an existing theory or a new theoretical concept. A case

    studys unit of measurement is associated with the entity concept.

    A research work deploying the case study method may have single or

    multiple cases. Conclusion could be drawn up from similarities or

    differences among the cases involved in a research work.

    Example: Mobiles and Micro-trading

    Aunty Akosua (hereafter referred to as AA) is a tomato retail trader. She has junior

    high school level education and has been working as a tomato retailer since June

    2008. AA works with Jane who serves as an intermediary between her and the

    farmers in the villages. Jane buys the tomatoes at wholesale prices from the

    farmers and AA retails them at the market.

    Prior to owning a mobile phone, communication between AA and Jane was

    constrained by distance. The limited access to Jane often contributed to poor

    inventory management, where AA could be out of stock of tomatoes for a week. In

    such scenarios, AA had to buy from other wholesalers, and that increased her

    coordination costs. She was then advised by a friend to get a mobile phone for

    Jane and herself, in order to enhance communication and reduce the cost and risk

    of frequent long journeys. In December 2008, AA purchased a used Samsung

    D500 for herself and a Nokia 3315 for Jane. The cost of Janes mobile phone was

    deducted from her earnings from trading with AA. They are both using TiGO as

    their service provider.

    Case Study

    The focus of the research is on process. The question is

    focused on what can be learned from this particular

    case.

    Single case design is ideal for studying extreme cases,

    to confirm or challenge a theory or for cases where a

    researcher does not have access previously. Examples: A

    failure or success in a particular event or activity: Causing Financial Loss to a State Lessons from the

    Woyome Case

    Multiple case design is appropriate when a researcher is

    keen to use more than one case to gather data and

    draw up conclusion based on the facts retrieved.

    Multiple case design serves to confirm evidence which

    enhance the reliability and validity of a research work.

    Case Study

    Intrinsic case study tends to focus on the

    case itself based on its uniqueness or usual

    contribution

    For example, Exploring lessons from a

    particular project or initiative or evaluating a

    particular projects or initiative:

    Effective management of public sector projects

    lessons from the GCNET system in Ghana

    the researcher reports the meaning comes

    from learning about an unusual situation (an

    intrinsic case). As Lincoln and Guba (1985) mention, this phase constitutes the lessons learned

    from the case.

    Analyzing Case Study

    The type of analysis of these data can be a holistic analysis of the

    case or an embedded analysis of a specific aspect of the case (Yin,

    2003) .
