A developmental psychologist conducts an observational study to investigate prosocial behaviour in nursery-aged children. To record instances of helpfulness, they design a detailed coding system. To ensure that the recording of behaviours is objective and consistent, two researchers independently observe and tally the same group of children during a play session. The researchers then calculate a correlation coefficient between their tally scores.
