positive relationship
In mathematics, a positive relationship refers to a situation where an increase in one quantity is associated with an increase in another quantity
In mathematics, a positive relationship refers to a situation where an increase in one quantity is associated with an increase in another quantity. Simply put, if two variables have a positive relationship, it means that as one variable increases, the other variable also increases. Similarly, if one variable decreases, the other variable decreases as well.
When representing a positive relationship on a graph, the points will exhibit a general upward trend. For example, if we have a scatterplot with two variables, such as the number of hours studied and the test score obtained, a positive relationship would mean that as the number of hours studied increases, the test score also increases.
One way to quantify the strength of a positive relationship is by calculating the correlation coefficient. This value ranges from -1 to +1. A positive correlation coefficient, close to +1, indicates a strong positive relationship between the variables.
It is important to note that a positive relationship does not necessarily mean that one variable causes the other. It simply indicates that the two variables tend to move in the same direction.
