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 0.793. 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.

Correlation is a measure of linear relationship.

Step-by-step explanation:

We are given that a correlation of 0.793 was found between the items answered and the mean score in a test.

Correlation helps us to to know how to variables are related to each other.It is a statistical technique  that help us to know type of relation between two variable. It may be a direct relation or a inverse relation.In other word, correlation is basically a measure of linear relationship between two variables.The correlation ranges from -1 to 1. A correlation between 0.7 and 1 is considered to be a strong correlation.A correlation of 0.793 means that there is a strong linear relationship between the two variables.Yes, there is a linear relationship between the number of questions answered and the mean score of test.So, it can be said as the number of questions answered increases, the mean score increases as well.
