participant observation
non-participant observation
participant observation
A correlation of r=-0.76 indicates a strong or weak correlation
a strong correlation

positive correlation
Two researchers observe students in a cafeteri to record behavior. What is one ethical issue?
consent or right to withdraw
Why might a researcher choose one unusual participant instead of 100 typical participants?
large representative sample may not be realistic

inter-observer reliability
Which is the strongest correlation?
-.84
+.24
-.96
-.96
A study in which the observer records only a limited range of behaviours.
structured observation
A psychologist spends eight months investigating one student with an unusually strong autiobiographical memory, the psychologist uses interviews, memory tests, school records, and observations What is the research method
case study
What is triangulation in research?
comparing evidence from different sources

a weak correlation
The role of the observer is NOT obvious to the participants
covert observer
Which is the weakest correlation?
-.05
+.06
-.05
Why can a unique case be difficult to replicate?
low generalisability because a unique case may not represent other people
What is the difference between structured vs. unstructured observation?
structured makes it more reliable and gives the observers definite categories they are observing

scatter graph
