A developmental psychologist is investigating aggressive playground behaviour in primary school children. Two trained observers independently watch the same video recordings of 20 children during break time and tally the number of aggressive acts displayed by each child. The researchers then calculate a correlation coefficient (rrr) between the two sets of tallies to determine the consistency of their observations.

Concurrent validity
Inter-rater reliability
