The correlation coefficient, denoted as ( r ), ranges from -1 to +1. A coefficient of -1 indicates a perfect negative correlation, meaning that as one variable increases, the other decreases in a perfectly linear manner. Conversely, a coefficient of +1 indicates a perfect positive correlation, where both variables increase together.<\/p>\n\n\n\n<p>Here\u2019s how to interpret the given options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>A: -0.9<\/strong>: This value indicates a very strong negative correlation. It suggests that there is a significant inverse relationship between the two variables. For instance, if one variable increases, the other tends to decrease substantially. A correlation of -0.9 implies that the relationship is quite consistent and predictable.<\/li>\n\n\n\n<li><strong>B: -0.2<\/strong>: This indicates a weak negative correlation. The relationship between the two variables exists but is not strong; changes in one variable do not consistently relate to changes in the other.<\/li>\n\n\n\n<li><strong>C: +0.2<\/strong>: This indicates a weak positive correlation, suggesting that as one variable increases, the other also tends to increase, but not strongly.<\/li>\n\n\n\n<li><strong>D: +0.9<\/strong>: This indicates a strong positive correlation. As one variable increases, the other increases significantly as well.<\/li>\n<\/ul>\n\n\n\n<p>In summary, a strong negative correlation (like -0.9) suggests a robust and predictable relationship where an increase in one variable leads to a notable decrease in the other. Understanding this concept is crucial in various fields, such as economics, psychology, and health sciences, where relationships between different factors are analyzed to inform decision-making and predictions.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following represents a strong negative correlation?A -0.9B -0.2C +0.2D +0.9 The Correct Answer and Explanation is : The correct answer is A: -0.9.
