A positive correlation exists when one variable decreases as the other variable decreases, or one variable increases while the other increases.
Which two variables are most likely to have a positive correlation?Positive correlation exists when two variables move in the same direction. One of the most common positive correlations is the relationship between demand and price.
What is an example of a positive correlation?Common Examples of Positive Correlations
The more time you spend running on a treadmill, the more calories you will burn. The longer your hair grows, the more shampoo you will need. The more money you save, the more financially secure you feel. As the temperature goes up, ice cream sales also go up.
Is 1 a perfect positive correlation?A correlation coefficient of +1 indicates a perfect positive correlation. As variable x increases, variable y increases. As variable x decreases, variable y decreases. A correlation coefficient of -1 indicates a perfect negative correlation.
