Two student researchers wish to determine the degree of observer 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 the observed student greeted the other person.Which of the following measures should the student researchers use to assess observer reliability?

The percentage agreement measure is the most appropriate measure to assess observer reliability in this scenario as it compares the frequency of agreement between the two observers. It is calculated by dividing the number of agreements by the total number of observations made and multiplying by 100 to obtain a percentage. This measure is commonly used in inter-rater reliability studies. Spearman's rank-order correlation assesses the degree of association between the rankings of two variables and is not appropriate for this study. The interobserver coding measure and overall agreement measure are not standard measures of observer reliability.
