ADDRESSING WEAKNESSES
OF QUANTITATIVE RESEARCH
oRigorin doing quantitative research
procedures
oAddition of qualitative analysis using quotes
of subjects (persons from whom data are
collected) to support statistical results
THINK-PAIR-SHARE:
Answer the Activity Sheet.
When it comes to a person's
personal improvement though, it is
importantfor them to find and
understand their weaknessesas
well, if they wish to grow and
improve to their fullest potential.
Knowingyour weaknessesis as
importantas knowingyour
strengths.
