Sampling
Basic sampling technique where we select a group of subjects (a sample) for study from a larger group (a population), each individual has an equal chance of being included in the sample.
What is random sampling?
Information between a participant and researcher(s) cannot be shared with anyone.
What is confidentiality?
Random allocation of participants into groups and comparison between these groups.
What is independent measures?
Recruiting volunteers in a quick and relatively easy method of sampling
What is self selected sampling?
Participants must be aware of all the potential risks and costs involved in the experiment.
What is consent?
Researchers use matching to form the groups. This design is preferred when the researcher finds it important that the groups are equivalent in a specific variable.
What is matched pairs?
The researcher divides the population into separate groups. Then, a probability sample (often a simple random sample) is drawn from each group.
What is stratified sampling?
Procedure that is conducted after experiment where all elements of the study are discussed in detail.
What is debriefing?
The same participants take part in each condition of the independent variable. This means that each condition of the experiment includes the same group of participants.
What is repeated measures?
Recruiting participants who are easily available
What is convenience or opportunity sampling?
The right to participate or opt out from a study at any time and for any reason during the research if they wish to.
What is withdrawal rights?
