Population

Sample
the process of choosing a sample
Sampling
a list of the items or people forming a population from which a sample is taken
Sampling Frame
- Accurate representation of the entire population is needed in the sample.
- used in quantitative research.
- Statistical analysis of the population.
Probability
- population can not/does not need to be sampled to represent the target population.
- the researcher is selective of its population and sample.
- used in qualitative research.
Non-probability
- Samples are targeted and selected based on a criterion set by the researcher.
- Criteria are based on the research objectives and questions.
Example: a study about smoking habits would only select individuals who are smokers.
Purposive Sampling
- looking for a specific characteristic in individuals that may or may not directly link to the research questions/objectives.
- age, sex, religion
Quota Sampling
using this kind of sampling technique involves selecting people that are the most convenient for you as a researcher. You may use someone you already know as a respondent because it will save you time and effort in looking for someone who will participate in your study.
Convenience Sampling
This is done by asking relevant people if they know someone who will be willing to participate in your research.
Snowball Sampling
this is a type of sampling that takes sample or respondents that are readily available. For example, you may choose respondents in your community where you can just pick anyone within a close range.
Opportunistic Sampling
1-10 subjects
phenomenology
20- 30 individuals
grounded theory
4-5 respondents
case studies
single culture-sharing group
ethnography
