For the below diagram, state (if possible) the direction (positive/negative), form (linear/ non-linear) and strength (strong/moderate/ weak/zero) of the relationship.

For the below diagram, state (if possible) the direction (positive/negative), form (linear/ non-linear) and strength (strong/moderate/ weak/zero) of the relationship.

If the two variables do not have linear relationship between them then they have a correlation coefficient equal to
