A researcher wants to determine the relationship between the time spent studying and the scores on a test. They have collected data from 50 students and calculated Pearson's r correlation coefficient to be 0.75. What can the researcher conclude about the relationship between the time spent studying and the test scores based on this value of Pearson's r?
