__________ does not always equal causation. Just because 2 variables/data sets trend together, doesn't mean they are related in any way to one another.

Succeeds in showing change in a statistic/variable over a period of time.

Independent Variable = ?

• Heart BPM (beats per minute)

• Time of exercise (in minutes)

• Untrained (non-athlete) Person Data

• Trained Athlete Data

Dependent Variable = ?

• Heart BPM (beats per minute)

• Untrained (non-athlete) Person Data

• Trained Athlete Data

How would you describe the correlation between time spent exercising and heart beats per minute?
