These are the slides I use in a short presentation introducing the idea of using software for data analysis to doctoral students

Computer Aided Qualitaitive Data Analysis Software

  1. 1. CAQDAS software (and one oddity!) Julian Beckton
  2. 2. Qualitative data <ul><li>Qualitative data includes text, visual,and multimedia information. </li></ul><ul><ul><li>Background information </li></ul></ul><ul><ul><li>Primary data </li></ul></ul><ul><ul><li>Secondary data </li></ul></ul><ul><ul><li>Relevant supporting information </li></ul></ul><ul><li>All of this data has to be managed and some of it has to be analysed. </li></ul>
  3. 3. Software typology <ul><li>Text retrievers/Textbase managers </li></ul><ul><li>Code and retrieve packages/theory builders/conceptual network builders </li></ul><ul><li>Based on Lewis & Silver, (2007) Using software in Qualitative Research. - Sage </li></ul>
  4. 4. Code based theory builders <ul><li>Enable thematic coding of chunks of data </li></ul><ul><li>Allow reduction of data along thematic lines </li></ul><ul><li>Can search text, and codes </li></ul><ul><li>Can record relationships between issues concepts and themes </li></ul><ul><li>Can develop more detailed codes where certain conditions combine in the data. </li></ul>
  5. 5. Text based tools <ul><li>Essentially allow sophisticated searching of text and language </li></ul><ul><li>Use thesauri to find words with similar meaning </li></ul><ul><li>Provide word frequency tables </li></ul><ul><li>Provide easy KWIC retrieval </li></ul><ul><li>Aimed at researchers who are focused on textual analysis </li></ul>
  6. 6. Implications of using software <ul><li>Data preparation is very important. </li></ul><ul><li>Not all data is computer readable! </li></ul><ul><li>Not necessary to use every feature available in a software package </li></ul><ul><li>Most functional not necessarily the best for you </li></ul>
  7. 7. Structure of a CAQDAS package <ul><li>All your files are contained in a “Project” </li></ul><ul><li>All packages maintain a database of your files. </li></ul><ul><li>Most packages designed to handle text which means that the format of imported text matters. </li></ul><ul><li>Some packages can handle multimedia. </li></ul>
  8. 8. Benefits <ul><li>Researcher is much closer to data </li></ul><ul><li>Easy to “explore” data. </li></ul><ul><li>Many packages allow annotations of text </li></ul><ul><li>Text can be coded – multiple codes can be applied to one piece of text </li></ul>
  9. 9. Writing and output <ul><li>Many CAQDAS packages offer writing tools. </li></ul><ul><li>Many offer different ways to sort and retrieve content. </li></ul><ul><li>Most offer output to Word, Excel or SPSS </li></ul><ul><li>Many offer graphic representations of your coding schema. </li></ul>
  10. 10. Working with a CADQAS package <ul><li>Know your methodological approach first! </li></ul><ul><li>Don’t expect it to work for you from the start </li></ul><ul><li>Keep one project for each research project. </li></ul><ul><li>Do thoroughly familiarise yourself with writing and memo tools </li></ul><ul><li>Come out of the software when you need </li></ul>
  11. 11. Some packages <ul><li>Nvivo (Very expensive, but market leader) </li></ul><ul><li>The Ethnograph (Slightly cheaper, and well featured) </li></ul><ul><li>Weft (Free, but very limited functionality) </li></ul><ul><li>There are others but we don’t have time to go through them. </li></ul>
  12. 12. Nvivo <ul><li>Off campus you need to buy a personal license (£130 for a student 12 month license. A full license is £330.00 ) </li></ul><ul><li> </li></ul><ul><li>Available to students on campus only </li></ul>
  13. 13. The Ethnograph <ul><li>Full license is ($299.00) </li></ul><ul><li> </li></ul><ul><li>Not supported by the university </li></ul><ul><li>Student license available for $99.00 </li></ul>
  14. 14. Weft <ul><li>Very limited functionality – essentially coding, retrieval and memo only. </li></ul><ul><li> </li></ul><ul><li>Completely free! </li></ul>
  15. 15. And the oddity! <ul><li>Zotero </li></ul><ul><li>Helps you collect manage and cite your resources. (Not ideal for data) </li></ul><ul><li>An extension to the Firefox internet browser. </li></ul><ul><li>Free. (But, you MUST be using Firefox) </li></ul>
