Define one completed visit consistently, for example a learner finishing a refill. Use the same observer, station and \(10\)-minute duration each time; count every completed visit, including repeat visits by the same learner.

Use a table with columns “Day”, “Break count” and “Lunch count”. Compare the three daily pairs and the totals; equal observation lengths make the total counts comparable.

A higher lunch total supports the prediction for these observations, but three days at one station do not establish what happens on every day or at every station. Other plans are acceptable if their measurement, comparison and limitation are clear.

Answer

One possible plan: count completed visits during each fixed period, record paired break/lunch counts for three days, compare totals or daily averages, and restrict conclusions to the observed periods.
