IV. QUALITATIVE DATA ANALYSIS
2. THREE BASIC PROCEDURE:
Description – Classification - Connection
•
Step 1: Phenomenon description
Purpose: to form/create concepts
Technique: open coding
Guide:
+ Retrieve abstract concepts from concrete raw data
+ Locate themes & assign initial codes/labels to pieces of
raw data bearing the same meanings
+ Condense mass data into codes/concepts
+ Theoretical framework may help
+ Open to change / flexible manner / back and forth
28/05/14

Guide:
+ Connect concepts / arrange them into sequences
+ Compare/contrast to identfy possible relations
+ Form overall connections among concepts
