technical terms about qualitative
research sampling techniques.
b. Compare-contrast the sampling
methods.

5. SAMPLE
Sample constitute the chosen ones
through which you will derive facts
and evidence to support claims or
conclusions propounded by your
research problem.

6. POPULATION
Population is the bigger group
from where you choose the sample.

7. SAMPLING
Sampling refers to the method or
process of selecting respondents or
people to answer questions meant
to yield data for a research study.

8. VENUE

11. SAMPLE VENUE, POPULATION, SAMPLE AND
SAMPLING SCHEME
This study was undertaken at Rizal National High School located
at Adela, Rizal, Occidental Mindoro with a total of 25
respondents.
The convenience sampling scheme was used in this study.
According to Helen Barrat 2009, convenience sampling is the
selection based on availability and willingness to take part.
Useful results can be obtained, but the results are prone to
significant bias because those who volunteer to take part may
be different from those chose not to, and the sample may not
be representative of other characteristics such as age or sex.
