On an international exam, students are asked to respond to a variety of background questions. For the 41 nations that participated in the exam, the correlation between the percentage of items answered in the background questionnaire (used as a proxy for student task persistence) and mean score on the exam was 0.894. Does this suggest there is a linear relation between student task persistence and achievement score? Write a sentence that explains what this result might mean.
