Answer :
the main answer is option a, -0.72, represents the strongest relationship among the given correlation values.
The correlation coefficient measures the strength and direction of the relationship between two variables. A correlation value of 1 indicates a perfect positive relationship, while a value of -1 indicates a perfect negative relationship.
The closer the correlation value is to 1 or -1, the stronger the relationship. Among the given correlation values, the strongest relationship is represented by the correlation coefficient of -0.72 (option a).
This value is closest to -1, indicating a strong negative relationship between the variables being analyzed.
The correlation value of -0.72 suggests that as one variable increases, the other variable tends to decrease consistently.
For example, if we are analyzing the relationship between studying hours and test scores, a correlation coefficient of -0.72 would indicate that as studying hours increase, test scores tend to decrease. This negative correlation suggests a strong inverse relationship between the two variables.
