Answer: B) Negative association
=================================================
Explanation:
We can draw a straight line fairly close to all of the points. This line is known as the regression line, or line of best fit. Since this line has a negative slope, we consider the points to have negative association.
Put another way: as x goes up, y goes down, or vice versa. The two work opposite variables do opposite actions.
-----------------
Extra info:
- Positive linear association would be when x and y go up together, or go down together. The variables go in the same direction together. The regression line would have positive slope.
- Points with no linear association would either be randomly scattered points, or perhaps another function type (eg: quadratic) would fit the points.
- The term "trend association" just seems to be something your teacher made up in order to possibly confuse students.
