Seeks to provide a rich understanding of a certain research
issue

2. QUANTITATIVE RESEARCH METHODOLOGIES

Quantitative research…
1. Quantifies variation
- What factors influence athletic ability?
Expresses a number or measure of a mount
2. Predict relationships
- When is it most likely to rain?
3. Describle characteristics
- What is the average height of an FTU student?

3. QUALITATIVE vs. QUANTITATIVE
RESEARCH
QUALITATIVE
• Textual data
• Explore phenomena
• Flexible, unstructured
• Describe variation,
relationships, and
individual and group
experiences.
QUANTITATIVE
• Numerica data
• Confirm hypotheses
• Rigid, structured
• Quantify variation,
predict relationships,
and describle
characteristics.

13. SAMPLING
Determining a Sample

- Even if it were possible, it is not necessary to
collect data from everyone in a community.
- In qualitative research, the researcher needs to
define and select a sample.
- The study’s objectives and the characteristics
of the study population determine which and
how many people to sellect.

14. SAMPLING METHODS

Three of the most common sampling menthods are:
Purposive sampling
Qouta Sampling
Snowball Sampling

15. SAMPLING METHODS

Purposive sampling
Purposive sampling groups participants according to
pre – selected criteria relevant to a particular research question
Ex: Motorbike drivers in HCMC
Sample sizes depend on:
- Resources and time available
- The study’s objectives
If the researcher needs a specific number
of participants, qouta sampling is better.

16. SAMPLING METHODS

Qouta Sampling
Quota sampling begins with two decisions:
-What characteristics?
- How many people?
Characteristics are selected in order to find participants
who have experience with or knowledge of the research topic
The researcher goes into the community and selects
the predetermined number of people demonstrating
the pre – selected characteristics

17. SAMPLING METHODS

Snowball Sampling
Snowball Sampling is a form of purposive sampling
Paticipants refer the researcher to orther potential participants
Snowball Sampling is often used to find and recruit
“hidden populaions” – groups not easily accessible

18. QUALITATIVE METHODOLOGIES
Your way of collecting data will depend on wich
qualitative methodology you choose. These include:
