Direction: Slightly positive with starting at bottom left moving up.
Strength: Most of all data is close together which means it is pretty strong.
Shape: The shape of this data seems to be linear in a sense.
When talking about the length of the foot having any relationship to the forearm of that same person the equation is what to look at for the answer. In this case, when a length of the foot is at zero the arm span is at 1.584 centimeters. As one centimeter is added to the foot of that person a total of -11.07 centimeters are subtracted from the forearm. This means as X increases Y decreases, thats where the negative slope comes in.
When looking at this residual plot you can see that that this fits the data pretty close. This means that this line is strong enough for this bunch of data. Since there is only a little bit of cluster and the data seems to going down you can see something is negatively happening.
