SUMMARY 1: Research Design ~Sampling

After Adibah Halilah and Rahayu presenting on this chapter, I can summarize the presentation as follow:

What is a sample?
A sample refers to a small group of people studied to collect information to draw conclusion about the larger group.


What is sampling?
Sampling refers to process of selecting the people (individuals) to be observed (studied).
 
What is a population?
A population refers to all the members of a particular group. It is the group of interest to the researcher, the group to whom the researcher would like to generalize the results of a study.

Target Population vs. Accessible Population
Target Population refers to the ideal/ actual group that researchers like to generalize.
Accessible Population refers to the population who researchers are able to generalize.

Random vs. Non Random Sampling
Random sampling methods include simple random sampling, stratified random sampling, cluster random sampling, and two stage random sampling.
Non Random sampling methods include systematic sampling, convenience sampling, and purposive sampling.
