The question "How many different states have you visited?" is a statistical question because:
1. Many people can answer the question: This question can be answered by a variety of individuals, each providing their own unique response based on the states they have visited.
2. The data collected helps us understand the differences in a group of people: By gathering responses from multiple individuals, we can analyze the data to understand the travel patterns and preferences within a group. This allows us to see variations among individuals in terms of the number of states they have visited.
Therefore, the question is considered a statistical question because it allows for multiple responses from different individuals and provides data that can be used to analyze and understand group differences.
