The relationship between thow variables x and y is also referred to as correlation. It is a measure that measures the strengthbof linear relationship between two variables. The relationship can be casual (if the ovcurence of the firsy variable causes the other), positive (if both variables move in tandem)....In the casecof the graoh on the picture there is no distinctcrelationship between x and y. Correct answer:D

Answer:

Option D,

Explanation:

The graph here looks unstructured and multi directional. The X and Y variable exhibit no signs of relationship between them.  Hence, the co-relation between X and Y graph is very poor or there exists no co-relation between X and Y variable. In short there is no way to determine value of Y if value of X is known or vice versa. Such scattered graphs lead to no relationship.

hence, option D is correct
