Describing the Nature of an Association

APSTAT-YH6JCI

A study was designed to measure the association between adults' resting pulse and their exercise pulse, which were both measured in beats per minute (bpm). Subjects measured their resting pulse for one minute. They than ran on a treadmill for two minutes and measured their exercise pulse immediately after for one minute.

The scatterplot below displays the information:

B

There is a relatively strong positive linear association between exercise pulse and resting pulse among adults.

C

There is a weak negative linear association between exercise pulse and resting pulse among adults.

D

There is a weak positive linear association between exercise pulse and resting pulse among adults.

E

There is relatively strong positive non-linear association between exercise pulse and resting pulse among adults.
