Participants Flashcards
Participants
Target populations
The group of individuals that a researcher is interested in studying e.g. people in the UK.
Participants
Sampling frames
A group/population that is identified when it is unrealistic to study the whole target population e.g. people in London.
Participants
Random sampling
A sampling technique where participants are selected from the sampling frame, where everyone has an equal chance of being selected.
Participants
Opportunity sampling
A sampling technique where participants are selected at the researcher’s convenience without knowing any details about the sample in advance
Participants
Systematic sampling
A sampling technique where every nth person on a list is selected by the researcher.
Participants
Stratified sampling
A sampling technique where the target group is divided into subgroups, e.g. by sex, and then the participants are selected randomly from each subgroup.
Participants
Quota sampling
A sampling technique where the target population is divided into subgroups, e.g. by sex, and the participants are chosen from each subgroup at the convenience of the researcher.
Participants
Self-selected/Volunteer sampling
A sampling technique where participants volunteer (select themselves) for research e.g. they come forward/respond to the psychologist after reading an advertisement in a newspaper or on a notice board.
Participants
Snowball sampling
A sampling technique where participants are initially recruited by the psychologist and then those participants recruit further participants from people they know, therefore the sample group appears to ‘snowball’.
Partcipants
Observational sampling techniques
Where participants are observed by the psychologist, who records a specific behaviour (event) each time it occurs to create a total score.
