Are we measuring what we want to measure- reliability means nothing without validity: reliability how close the points are together, validity: falling on the bullseye. Types of measurement: systematic observation, watching children and record what they say or do. Naturalistic observation: behaviours observed in real life situation. Example: children playing on their school playground and observing either via the naked eye or video. Structured observation: researcher creates setting likely to elicit behavior of interest (some situations are un-common, thus researchers must make the situation: example: child plays a few games; experimenter pretends to drop objects. Observe if child approaches or withdraws from stranger. Behavioral coding: operational definition: what exactly does the behaviour look like.
