cesar wants to determine whether students who eat breakfast in the morning receive higher grades in their fist-period class. does the scenario describe a statistical question that would best be answered by an observational study

Question

answer choices:

yes, an observational study would be best for this scenario because a treatment is not being applied to the sample

yes, an observational study would be best because the sample is not included in the overall population

no, an observational study would not be best because it is not an ethical study

no, an observational study would not be best because the study required collecting opinions from participants

Answer 1

The correct answer is:

Yes, an observational study would be best for this scenario because a treatment is not being applied to the sample.

In this case, Cesar is looking to observe and analyze existing behaviors (eating breakfast) and their potential effects on student grades without manipulating any variables or assigning any treatments to the participants. An observational study is appropriate in such scenarios.
