Question

A correlation coefficient is a numerical value that ranges from -1 to +1 and measures the strength and direction of a relationship between two variables. A correlation coefficient of 0 means that there is no relationship between the variables, while a correlation coefficient of 1 means that there is a perfect positive relationship between the variables. Based on the information given in the question, it is clear that there is a positive relationship between listening to music and happiness, and therefore the correlation coefficient should be positive. Since the correlation coefficient cannot exceed 1, the most likely correlation coefficient in this case is 0.27, which indicates a moderate positive relationship between the variables. Therefore, the correct answer is D) 0.27.
