• A positive correlation means that as one variable increases, the other variable also tends to increase.

• A positive correlation means that as one variable increases, the other variable tends to decrease.

• A positive correlation indicates that there is no relationship between the variables.

• A positive correlation means that both variables are constant and do not change.
