Why is instant data, like the number of rabbits in a field at a single moment, generally less reliable than long-term data, like the average number of rabbits in the field over 10 years? A) Instant data is often collected by just one person. B) Those collecting instant data may not know where to look for it. C) A single data point is less reliable than multiple data points because it may not be representative. D) Interpretations of instant data may vary among people.

- The correct answer is: C) A single data point is less reliable than multiple data points because it may not be representative.
- Instant data, collected at a single moment or time frame, may not accurately represent the overall trends or patterns occurring in a system. It captures only a snapshot of the situation at that specific instance, potentially missing variations or fluctuations that occur over time. Long-term data collected over a period, such as 10 years, provides a broader perspective and more comprehensive information about trends, patterns, and variations within the system.
- Reliability in data collection involves obtaining a representative sample that accurately reflects the entire population or system being studied. Instant data, taken at a specific moment, might be influenced by various factors like random fluctuations, unusual circumstances, or specific events occurring at that time, making it less reliable for drawing general conclusions about trends or behaviors over the long term. Multiple data points over an extended period help to mitigate the influence of such individual fluctuations, providing a more accurate and reliable picture of the overall scenario.
