When curating data, sometimes it is easier to see patterns if you use a sector plot instead of the classic Cartesian coordinate system. Here is an example of a sector plot with sector angles proportional to
30
and radii proportional to
50-x
for
x
values ranging from 30 to the number of data points. The curve is spiraling inward while the angle remains constant. Thus from a visual inspection, it is evident that a negative linear relationship is present.
