Importance of the measurement: must be reliable and valid, directly relevant for the hypothesis. Reliability: degree to which the measurements are consistent (same results) Interrater reliability: how much agreement among different observers. Test-retest reliability: measurement of a performance on the same test (same conditions) are similar on two or more occasions. Validity: degree to which the experiment measures what it is intended to measure. Internal validity: whether observed objects are due to the conditions. Structured interview: goal is to collect self-reports on the same topic from everyone being studied, ask many children the same question.
