  1. AN INTRODUCTION TO QDA MINER: orIS QDA MINER REALLY A BETTER SOLUTION FOR MIXED METHODS RESEARCH? By Normand Péladeau President Provalis Research Corp.

  2. MIXED METHODS INTRADITIONNAL CAQDAS • Integration of numerical data • Inclusion of socio-demographic data, responses to closed-ended questions, etc. • Limited ability to perform comparisons & no statistics • Performing statistics on/with qualitative data • Export code frequency matrix to file • Open statistical software • Import saved matrix • Run statistical analysis

  3. HOW DOES QDA MINER DIFFERS? • Same file format as SimStat (a stat software) and full interoperability between the two.Ability to keep numerical, categorical data, dates and text data in a single data file

  4. HOW DOES QDA MINER DIFFERS? • Same file format as SimStat (a stat software) and full interoperability between the two.Ability to keep numerical, categorical data, dates and text data in a single data file

  5. HOW DOES QDA MINER DIFFERS? • Same file format as SimStat (a stat software) and full interoperability between the two.Ability to keep numerical, categorical data, dates and text data in a single data file • Integration of statistical toolsFrequencies and percentages, F-test, chi-square, correlation, clustering, multidimensional scaling, correspondence analysis.

  6. STATISTICS ON QUALITATIVE DATA

  7. STATISTICS ON QUALITATIVE DATA

  8. HOW DOES QDA MINER DIFFERS? • Same file format as SimStat (a stat software) and full interoperability between the two.Ability to keep numerical, categorical data, dates and text data in a single data file • Integration of statistical toolsFrequencies and percentages, F-test, chi-square, correlation, clustering, multidimensional scaling, correspondence analysis.

  9. HOW DOES QDA MINER DIFFERS? • Same file format as SimStat (a stat software) and full interoperability between the two.Ability to keep numerical, categorical data, dates and text data in a single data file • Integration of statistical toolsFrequencies and percentages, F-test, chi-square, correlation, clustering, multidimensional scaling, correspondence analysis. • Integration of other text analysis techniques • Within QDA Miner itself • With WordStat (a content analysis add-on)

  10. INTEGRATING TEXT ANALYSIS TECHNIQUES Mixed Methods Qualitative Analysis Content Analysis Text Mining Information Retrieval Computational Linguistic ANALYSIS OFNUMERICAL DATA Statistical Analysis ANALYSIS OFTEXTUAL DATA

  11. QUALITATIVE  CONTENT ANALYSIS One can use codings in QDA Miner to control what will be analyzed by WordStat

  12. QUALITATIVE  CONTENT ANALYSIS

  13. CONTENT ANALYSIS  QUALITATIVE One can use WordStat text-mining features or dictionaries to search and code segments in QDA Miner

  14. QUALITATIVE + INFORMATION RETRIEVAL Information Retrieval Models • Boolean search ( AND, OR, NOT ) • Similarity search

  15. QUERY BY EXAMPLES

  16. QUERY BY EXAMPLES

  17. QUERY BY EXAMPLES

  18. QUERY BY EXAMPLES • Relevance feedback mechanism • Fuzzy string matching Resistant to misspelling Matches related words Ex.: “resistant to misspelling” “resistent to mispeling” “resist to misspelled words” “resist to words not correctly spelled”
