- Sampling techniques
- Random: every member of the target population has an equal chance of selection
- strength= not biased, equal chance
- limitation- researcher may still end up with a biased sample if sample is too small
- Opportunity: using whoever is available
- strength= easiest method because it takes less time to locate a sample
- limitation= biased because its drawn from a small part of target pop
- Volunteer: using whoever puts themselves forward
- strength= access a variety of participants- more representative and less biased
- limitation= biased- more motivated with less time on their hands
- Random: every member of the target population has an equal chance of selection
