A flow diagram illustrates the research process. The details are as follows:

 Research Question: Do tutored students have higher grades than non-tutored students?

 Study Methods: Grades of tutored students were compared with grades of non-tutored students.

 Data Analysis: Grade-point average of tutored students was 34% higher than grades for non-tutored students, and this difference cannot be easily explained by chance.

 Conclusion: Tutoring improves grades.
