What variables have a negative correlation?A negative correlation is a relationship between two variables in which an increase in one variable is associated with a decrease in the other. An example of negative correlation would be height above sea level and temperature. As you climb the mountain (increase in height) it gets colder (decrease in temperature).
Which of the following is an example of a negative correlation?The correct answer is A. (People who spend more time exercising tend to weigh less). Negative correlation refers to increase of the one variable parallel to a decrease of second variable. In this example, the amount of exercise has increased and the body weight has decreased.
Which of the following indicates negative correlation?In statistics, a perfect negative correlation is represented by the value -1.0, while a 0 indicates no correlation, and +1.0 indicates a perfect positive correlation. A perfect negative correlation means the relationship that exists between two variables is exactly opposite all of the time.
Is 0.5 A negative correlation?Negative correlation is measured from -0.1 to -1.0. Weak negative correlation being -0.1 to -0.3, moderate -0.3 to -0.5, and strong negative correlation from -0.5 to -1.0.
