Researchers studying types of play in children had two coders observe videos of pairs of children (dyads) who were left in a play room for 10 minutes. At each of three time points (T1, T2, T3), the coders judged whether the dyad was engaged in (i) no play, (ii) interactive play, or (iii) parallel play at that moment. The coders' judgments are presented in the table below. Coder 1 Coder 2 INTERACT PARALLEL NO PLAY INTERACT PARALLEL NO PLAY Dyad 1 T1 X X T2 X X T3 X X Dyad 2 T1 X X T2 X X T3 X X Dyad 3 T1 X X T2 X X T3 X Dyad 4 T1 X T2 X X X X T3 X X A. Using the Percentage of Agreement method (i.e., as you did in Lab 4), assess the interrater reliability of this observational measure. Calculate the statistic by hand. Provide the formula and show all your work/calculations. B. Would you conclude that this observational measure has acceptable interrater reliability? Why or why not? C. Briefly suggest two steps that researchers can take in an attempt to obtain higher interrater reliability in their studies.
