Question
The director of graduate admissions is analyzing the relationship between scores in the GRE and student performance in graduate school, as measured by a student’s GPA. The table below shows a sample of 10 students. GRE 1,150 1,290 100 750 1,270 1,210 1,210 480 870 1,680GPA 3.6 3.8 3.2 2.3 2.8 3.0 3.4 2.0 4.1 3.7 Click here for the Excel Data File Which of the following statements is correct?Multiple ChoiceThe correlation between GRE and GPA is positive and strong.The correlation between GRE and GPA is positive and weak.The correlation between GRE and GPA is negative and weak.The correlation between GRE and GPA is negative and strong.
Solution
To answer this question, we first need to calculate the correlation coefficient between GRE scores and GPA. The correlation coefficient is a statistical measure that calculates the strength of the relationship between the relative movements of two variables. The values range between -1.0 and 1.0. A calculated number greater than 1.0 or less than -1.0 means that there was an error in the correlation measurement.
A correlation of -1.0 shows a perfect negative correlation, while a correlation of 1.0 shows a perfect positive correlation. A correlation of 0.0 shows no linear relationship between the movement of the two variables.
Unfortunately, without the Excel Data File, we cannot calculate the correlation coefficient. Therefore, we cannot determine which of the multiple-choice options is correct.
