Two variables are said to be positively correlated if an increase in one is accompanied by an increase in the other. There need not be any causal link between these changes.

What are three types of correlation in maths?

In mathematics, the three types of correlation are positive correlation, negative correlation, and zero correlation. Positive correlation occurs when two variables move in the same direction, meaning that as one increases, the other also increases. Negative correlation happens when one variable increases while the other decreases. Zero correlation indicates no relationship between the two variables, meaning changes in one do not affect the other.

What is implied when it is said that x and y have a positive correlation?

When it is said that x and y have a positive correlation, it implies that as the value of x increases, the value of y tends to increase as well. This relationship suggests that there is a direct association between the two variables, meaning that higher values of one are associated with higher values of the other. Positive correlation can be quantified using a correlation coefficient, typically ranging from 0 to 1, where values closer to 1 indicate a stronger correlation.
