how do we develop behavioral categories?
behavioral categories
operational definitions
clarity of the definition: goals, hypotheses, simplicity, scope of the study
What are the advantages of recording behavior sequences?
f
How do we cope with complexity in observational research
time sampling, individual sampling, event sampling, recording
What are the interrater reliability thingies?
percent agreement: simplest method, should be 70%, will LIKELY underestimate or overestimate agreement
Cohen’s Kappa: allows you to determine if agreement observed is due to chance, BETTER THAN PERCENT
Pros/cons of using pearson correlation coefficient as an index of interrater reliability

cons:

Systematic difference between a true value and the value actually observed due to observer variation
