                               Goals
    • Discuss the difference between qualitative and quantitative 
      data and analysis
    • Enable you to analyze data gathered from: 
        Questionnaires
        Interviews
        Observation studies
    • Make you aware of software packages that are available to 
      help your analysis
    • Identify common pitfalls in data analysis, interpretation, and 
      presentation
    • Enable you to interpret and present your findings in 
      appropriate ways
                                 www.id-book.com                    2
         Quantitative and qualitative
    Quantitative data: Expressed as numbers
    Qualitative data: Difficult to measure sensibly as 
    numbers, for example, count number of words to 
    measure dissatisfaction
    Quantitative analysis: Numerical methods to ascertain 
    size, magnitude, and amount
    Qualitative analysis: Expresses the nature of elements 
    and is represented as themes, patterns, or stories
    Be careful how you manipulate data and numbers!

               Basic quantitative analysis
        • Averages: 
             Mean: Add up values and divide by number of data points
             Median: Middle value of data when ranked
             Mode: Figure that appears most often in the data
        • Percentages
        • Be careful not to mislead with numbers!
        • Graphical representations give overview of data
                                               Number of errors made

               How question design affects 
                          data analysis
     • Question design affects analysis 
        Open question: Each answer analyzed 
        separately
        Closed question: Analyzed quantitatively
     • Fixed alternative answers restrict what can 
        be said in findings
                                www.id-book.com
                                                                    4
                Basic qualitative analysis
    • Looking for critical incidents
         Helps to focus in on key events
         Then analysis can proceed using specific techniques
    • Identifying themes
         Emergent from data, dependent on observation framework if used
         Inductive analysis
    • Categorizing data
         Categorization scheme pre-specified
         Deductive analysis
    • In practice, combination of inductive and 
       deductive
