Generate two coloured Scatter Plots : first mean radius versus mean perimeter , then mean radius versus mean area . Put radius on the x-axis in both plots. Inspect the shape before using any correlation coefficients.
Which observation is supported?

Question

Generate two coloured  Scatter Plots : first  mean radius  versus  mean perimeter , then  mean radius  versus  mean area . Put radius on the x-axis in both plots. Inspect the shape before using any correlation coefficients. 
 Which observation is supported?

Accepted Answer

Radius–perimeter is nearly linear; radius–area is increasing but visibly curved, with area rising faster at larger radii.

Answer

Both relationships are exactly straight because all three features describe size.

Answer

The curvature proves that the app mixed up the two diagnosis labels.

Answer

Radius–area has no relationship because its points do not lie on a straight line.
