Inter-observer reliability- An observer may miss important details or may
only notice events that confirm their opinions or hypotheses. Observationists
should be consistent, which means there should be two observers and
ideally produce the same record of events. The extent to which two or more
people agree is known as inter observational reliability. It should be at least
80%.
Target behaviours should be observable and measurable.
Target behaviours should be broken down in a set of behavioural categories.
Summary: Target behaviours should be observable and measurable. They should also be broken
down in a set of behavioural categories. Target behaviours should be operational into observable
behaviours to reduce subjectivity (must be specific). Unstructured- lots of things going on.
Structured- organised and specific. Inter-observer reliability- 80% or above (essentially a peer
review between researchers).
