- Sampling Techniques
- Random Sampling
- When everyone in a sample has an equal chance of being chosen
- (e.g.) Names of participants may be drawn from a hat
- Strengths
- No researcher bias
- Most unbiased method
- Weaknesses
- A representative sample is not always guaranteed
- can be time consuming
- Not all selected participants will want to take part
- When everyone in a sample has an equal chance of being chosen
- Opportunity Sampling
- Selecting people that are readily available at the time
- (e.g.) approaching people in an area and asking them to participate
- Strengths
- Quickest and easiest form of sampling
- Most economical
- Weaknesses
- More likely to have a biased and unrepresentative sample
- Selecting people that are readily available at the time
- Self-Selecting
- When participants volunteer themselves to participate in the research
- (e.g.) Participants respond to posters seen online/in magazines/in university
- Strengths
- Participants are more willing to participate (less chance of withdrawal)
- Weaknesses
- Time consuming
- Sample more unrepresentative
- When participants volunteer themselves to participate in the research
- Snowball Sampling
- When participants recruit other participants for the study
- (e.g.) asking participants to recruit others and having those participants recruit others
- Strengths
- can be useful when researchers are researching niche target populations
- Weaknesses
- Not always reliable
- May be unrepresentative
- When participants recruit other participants for the study
- Random Sampling
