Question

Natalia notices that if she does not sleep a lot at night, she feels tired the next day. what relationship (if any) exists between hours of sleep and degree of exhaustion?

Answer 1

Answer: The relation is an inverse correlation.

An inverse correlation is present when two variables are connected in a way in which they move in opposite directions.

In this case, as sleep decreases (negative), exhaustion increases (positive) in a similar pattern.
