| Question | Answer |
| Sampling Unit | The people you want to conclude in your sample. |
| Sampling Frame | Creating a list of peoples names you want in your sample. |
| Random Sampling | Each person has an equal chance of being chosen |
| Advantages of Random Sampling | - Avoids interviewer boas while selecting the sample - Representative |
| Disadvantages of Random Sampling | - Time-consuming - Not a perfect cross-section of the population - Large sample is needed for true representation |
| Multistage Sampling | Selecting a sample from another sample |
| Advantages of Multistage Sampling | - Cheap - Quick |
| Disadvantages of Multistage Sampling | - Not random - Increase in sampling error |
| Systematic Sampling | It is a form of random sampling. The sample is selected at shorter regular intervals e.g. 7th person, 14, 21, 28... |
| Advantages of Systematic Sampling | - Quick / efficient - Less expensive |
| Disadvantages of Systematic Sampling | - Not truly random |
| Stratified Sampling | Another form of random sampling. Sampling frame is divided into smaller groups called strata based on certain criteria. |
| Advantages of Stratified Sampling | - More control - Requires smaller sample size - Representative |
| Disadvantages of Stratified Sampling | - Time consuming - Not truly random - Not practical |
| Quota sampling | Allow the control of variables without a sampling frame |
| Advantages of Quota Sampling | - Simple - Quick - Cheap |
| Disadvantages of Quota Sampling | - Less likely to produce a representative sample - Potential bias: researchers choose who they interview |
| Snowball Sampling | Getting people to give information about other people in order to then interview them |
| Advantages of Snowball Sampling | - Creates a sample where other methods fail to |
| Disadvantages of Snowball Sampling | - Not Random - Not representative - Relies on personal recommendations |
| Volunteer Sampling | Taking volunteersnto do the research |
| Advantages of Volunteer Sampling | - Allows researchers to question theories - Easy access to a sample - Quick to obtain the sample |
| Disadvantages of Volunteer Sampling | - Can include interviewer bias - Not representative - Not completely random |
| Which type of sampling is Representative | - Random sampling - Multistage sampling - Systematic sampling - Stratified sampling - Quota sampling |
| Which type of sampling is Not Representative | - Snowball Sampling - Volunteer Sampling |
