data

• Qualitative:  expressed in words

  + More richness and detail  → more internal validity - Harder to analyse : does not lend itself to being summarised statistically so that patterns and comparisons can be drawn .

  • Subjective interpretation of researcher
• Quantitative  : numerically +Objective less subject to bias → easier to analyse and draw conclusion -Narrower scope and meaning : not representative of real life
• Primary data : directly from ppts collected first hand  → specifically relate to aims 

  Secondary: third party → pre-existing not specific to research
