For
On horizontal axis: Body weight
On vertical axis: Backpack weight
Strength: In the scatterplot, the points do not lie very close together and do not spread far apart as well. Thus, strength will be moderately strong.
Form: In the scatterplot, no strong curvature exists. Thus, form will be linear.
Direction: Due to the upward slope of the pattern, the direction will be positive.
Unusual features: In the scatterplot, rightmost point appears to deviate significantly from the general linear pattern in the other points. Thus, one outlier exists.
