Two student researchers wish to determine the degree of interobserver reliability they achieved in their study.They observed individual students who were approaching another person on a campus path.The two observers both independently recorded whether or not each observed student greeted the other person.Which of the following measures should the student researchers use to assess interobserver reliability?
A) Pearson Product-Moment correlation
B) Spearman's rank-order correlation
C) interobserver coding measure
D) percentage agreement measure

The most appropriate measure for assessing interobserver reliability in this scenario is the percentage agreement measure, which calculates the proportion of observations on which both observers agreed. This would provide a concrete measure of the level of agreement between observers when recording whether or not students greeted another person on the campus path. The other measures listed (Pearson Product-Moment correlation and Spearman's rank-order correlation) are more appropriate for examining the degree of association between continuous variables, while the interobserver coding measure is not a widely used or established reliability measure.
