Question

a health website shares a scatter plot showing a positive relationship between hours of sleep per night and happiness levels. the headline reads, sleeping more directly increases happiness! a. what is wrong with this claim? b. write a more accurate headline for this data.

Explanation:

a. A scatter - plot showing a positive relationship only indicates correlation. Correlation does not imply causation. There could be other factors (confounding variables) that affect both sleep and happiness, or it could be that happier people tend to sleep better, not that sleep directly causes happiness.
b. A more accurate headline should reflect the correlational nature. For example, "There is a positive correlation between hours of sleep per night and happiness levels"

Answer:

a. The claim wrongly assumes causation from a correlational relationship.
b. “There is a positive correlation between hours of sleep per night and happiness levels”
