Study Notes
Sampling Methods
- Probability sampling: elements in the population have a known, nonzero chance of being selected as sample subjects.
- Advantages of probability sampling: representativeness and precision.
Types of Probability Sampling
- Simple random sampling
- Systematic sampling
- Stratified sampling
- Cluster sampling
Types of Non-Probability Sampling
- Convenience sampling
- Judgmental sampling
- Quota sampling
Case Study Analysis
- Identify the independent and dependent variables
- Identify the moderating variables
Research Design Strategies
- Surveys
- Questionnaires
- Observations
- Experiments
- Action Research
Terminologies
Population and Sampling
- Population: the entire group of people, events, or things of interest that the researcher wishes to investigate
- Element: a single member of the population
- Sample: a subset of the population that comprises some members selected from the population
- Subject: a single member of the sample
- Sampling: the process of selecting the right individuals, objects, or events as representatives for the entire population
Advantages of Sampling
- Less costs
- Less field time
- More accuracy
- When it’s impossible to study the whole population
Sampling Processes
- Define the population
- Determine the sample frame
- Determine the sampling design
- Determine the appropriate sample size
- Execute the sampling process
