Question

(c) ms. rivera studied her students chemistry test scores and tv habits. she found that students who watched less tv tended to earn higher scores on the test. what conclusion should she make?
there is no correlation between test score and amount of tv watched.
there is a correlation between test score and amount of tv watched. there is probably also causation. this is because there is an increase in a students test score with a decrease in the amount of tv watched.
there is a correlation between test score and amount of tv watched. there may or may not be causation. further studies would have to be done to determine this.

Explanation:

The problem describes an observed trend (less TV watching linked to higher test scores), which indicates a correlation. However, correlation alone does not prove causation—other factors (e.g., study time) could explain both behaviors. Further research is needed to confirm if reducing TV directly causes higher scores.

Answer:

There is a correlation between test score and amount of TV watched. There may or may not be causation. Further studies would have to be done to determine this.
