If the quantities simultaneously increase or decrease in value, a positive correlation exists. If one increases as the other decreases, a negative correlation exists. A cause. is something that makes something else happen. Out of two events, it is the event that happens first. To determine the cause, ask the question "Why Did it Happen?" An . effect

If the data points make a straight line going from the origin out to high x- and y-values, then the variables are said to have a positive correlation. If the line goes from a high-value on the y-axis down to a high-value on the x-axis, the variables have a negative correlation.

positive. correlation. If y tends to decrease as x increases, then the data have . negative. correlation. A correlation coefficient, denoted by r, is a number from -1 to 1 that measures how well a line fits a set of data pairs (x, y). If r is near 1, the points lie close to a line with a positive slope.
