Question

Nazanin is analyzing the relationship between the number of years first-year McMaster undergraduate students previously spent being classically trained on a musical instrument and the grade that they received in the course Math 1A03. She calculated a correlation coefficient of 0.25. Which of the following best describes the relationship between these variables according to Nazanin's results?

A) Strong positive correlation
B) Weak positive correlation
C) Strong negative correlation
D) Weak negative correlation

Answer 1

The correlation coefficient of 0.25 indicates a weak positive correlation between the years of classical music training and the Math 1A03 course grade.

Step-by-step explanation:

Nazanin is analyzing the relationship between the number of years of classical music training and the grade received in Math 1A03. She found a correlation coefficient of 0.25. According to this result, the relationship between the two variables is best described as a weak positive correlation. This means that there is a slight tendency for students who have more years of classical music training to score higher in the math course, but the relationship is not strong or highly predictive.
