you want to count the number of cars driving through the intersection of hi hope road and hurricane shoals road during school dismissal. what type of study is the best for this situation?
sample
observational study
survey
experiment

Explanation:

To determine the best study type, we analyze each option:

• Sample: Involves selecting a subset, not direct counting of all (or observed) cars.
• Observational Study: Involves observing and recording phenomena (like car counts) without interfering. Counting cars at an intersection during school dismissal is direct observation.
• Survey: Requires asking people (e.g., questionnaires), which is not suitable for counting cars.
• Experiment: Involves manipulating variables (e.g., changing traffic lights), which is not done here.

Thus, an observational study is best as it focuses on observing the natural behavior (car traffic) without intervention.

Answer:

B. Observational Study
