What are the Experimental designs
Repeated measures
Independent groups
Matched pairs
Repeated measures
The same participants are used in both conditions
Independent groups
Participants are randomly allocated to different groups which represent different conditions
Matched pairs
Pairs of participants are closely matched and are then randomly allocated to one of the experimental conditions
Random sampling
Everyone in the target audience had an equal chance of being selected
Opportunity sampling
Consists of those people available to the researcher at the time of carrying out the research
Volunteer sampling
Where the participant self-select, they volunteer themselves to take part
Stratified sampling
Subgroups are identified and participants chosen randomly from each subgroup
Systematic sampling
The researcher uses a pre-determined system to randomly select participant
Random sampling advantages
Unbiased
Random sampling disadvantages
Time consuming
Opportunity sampling strengths
Easiest method less time consuming
Opportunity sampling disadvantages
Biased
Not going to get a wider view
Volunteer sampling advantages
Less chance of drop out
Less time consuming
Les biased
Volunteer sampling disadvantages
May be biased in other ways as participants are likely to become motivated and/or extra time on their hands
