The r value is a number between -1 and +1.
For a negative value, the closer to -1 it would be a strong negative, if it is closer to 0, it would be a strong negative.
-0.31 is closer to 0 than -1, so it would have a strong negative association.
Answer:
A = {1,2,3} and B = {1,2,A,B}
A U B = { 1,2,3,A,B}
A U B means, the union of both sets. So, all the members in both sets are written together.
NB: An element is written only once even if it appears in both sets.
