Question

a grocery store is collecting data on dairy sales. the store made observational studies and performed experiments. move each scenario into the box to show which research design was used to collect the data. observational study experiment - the sales of dairy products from week to week is compared and analyzed. customers are mailed a coupon for dairy products to see if it affects their purchasing habits. data is collected on consumer purchases of dairy products between the hours of 3:00 pm and 7:00 pm. the arrangement of dairy products is rearranged for one week and the amount of dairy sales are recorded.

Explanation:

To solve this, we first recall the definitions:

• Observational Study: Collects data without interfering (just observing).
• Experiment: Involves manipulating a variable (treatment) to see its effect.

Step 1: Classify "The sales of dairy products from week to week is compared and analyzed."

This is observing sales over time without changing anything. So it’s an Observational Study.

Step 2: Classify "Customers are mailed a coupon for dairy products to see if it affects their purchasing habits."

Mailing coupons is a manipulation (treatment) to test its effect. So it’s an Experiment.

Step 3: Classify "Data is collected on consumer purchases of dairy products between the hours of 3:00 pm and 7:00 pm."

This is observing purchases during a time window without interference. So it’s an Observational Study.

Step 4: Classify "The arrangement of dairy products is rearranged for one week and the amount of dairy sales are recorded."

Rearranging products is a manipulation (changing layout) to test its effect on sales. So it’s an Experiment.

Final Categorization:

Observational Study	Experiment

(If you need to present the answer as moving each scenario to the box, the above table shows which box each scenario belongs to.)
