Question

1. which of the following classifications of variable types is false?

○ customer satisfaction: very unsatisfied, unsatisfied, satisfied, very satisfied → ordinal categorical
○ student height → continuous numerical
○ whether a student has previously taken a statistics course → categorical
○ population of each state in the us → continuous numerical

Explanation:

1. Analyze "Customer satisfaction": The categories (very unsatisfied, etc.) have an order, so ordinal categorical is correct.
2. Analyze "Student height": Height can take any value in a range (e.g., 160.5 cm), so continuous numerical is correct.
3. Analyze "Whether a student...": It has two categories (yes/no), so categorical is correct.
4. Analyze "Population of each state": Population is a count of people, so it's discrete (can only be whole numbers), not continuous. So this classification is false.

Answer:

Population of each state in the US → continuous numerical
