Question

Quizplus · Accepted Answer

Correlation would be the most appropriate research method to study the relationship between high school grades and college grades. Correlation measures the strength and direction of the relationship between two variables, in this case, high school grades and college grades. Dr. Santos can use a correlation coefficient to determine whether there is a positive or negative correlation between the two variables. This method would be more appropriate than an experiment or a survey, as a true experiment would require manipulating independent variables to see the impact on one dependent variable and it is not ethical to alter a student's high school grades for research purposes. A survey would rely on self-reported data, which may not always accurately reflect a student's actual grades.
