To ensure fair comparisons between locations during counts, you should?

• A. At the same time
• B. At different times
• C. In different months
• D. Only on weekends

Answer: (C)

The main idea is to control time as a variable when comparing locations. Counting results can vary a lot with when you measure, due to daily rhythms, weather, events, or seasonal factors. By conducting the counts at the same time across all locations, you keep this timing effect constant, so any differences you observe are more likely due to real differences between places rather than when you counted. If you count at different times, the numbers could reflect these time-related fluctuations rather than true contrasts between locations. Counting in different months introduces seasonal changes, and counting only on weekends can bias results toward weekend activity. So, you should count at the same time across locations to ensure a fair comparison.
