Controlled observations have some aspects controlled, allowing the researcher to control variables and achieve high internal validity and high replicability.
Overt observations require participants to know they are being observed, allowing them to give informed consent and potentially influencing their behaviour.
Design is a crucial aspect of observations, with various ways to record data including unstructured observation, structured observations, and non-participant observation.
Behaviour categories are referred to in observations, with the target behaviour to be studied needing to be precisely defined and made observable and measurable.
Sampling methods in observations include event sampling, which involves counting the number of times a particular behaviour occurs in a target group, and time sampling, which involves recording behaviour with a pre-established time frame.
Evaluations of observations in observations record what participants do, not why they do it, allowing for the capture of spontaneous and unexpected behaviour.
