A positive relationship exists when both variables increase

A positive relationship exists when both variables increase or decrease at the same time. True or False

Solution

Positive Correlation: Positive correlation indicates that both variables increase or decrease together, whereas negative correlation indicates that as one variable increases, so the other decreases, and vice versa Degree of relationship between two sets of information. If one set of data increases at the same time as the other, the relationship is said to be positive or direct. If one set of data increases as the other decreases, the relationship is negative or inverse. If there is no relationship between the two sets of data the relationship is said to be zero linear correlation. Correlation can be shown by plotting a line of best fit on a scatter diagram. The steeper the line drawn, whether positive or negative, the stronger the correlation. Therefore, answer is true.
