Coding (Berkowitz, 1997)

  • What patterns or common themes emerge?
  • Are there any deviations from these patterns? If so, how can these be explained?
  • What interesting ‘stories’ emerge from the responses?
  • Do any of these patterns suggest that additional data may be needed?
  • Do the patterns that emerge corroborate the findings of any corresponding qualitative analyses that have been conducted? If not, what might explain these discrepancies?
