Activity #3

Exercise Questions.

  • Study the examples and non-examples of Statistical Questions below, and complete the exercises that follow.

These three questions are examples of statistical questions:

  • What is the most common color of the cars in the school parking lot?
  • What percentage of students in the school have a cell phone?
  • Which kind of literature—fiction or nonfiction—is more popular among students in the school?

These three questions are not examples of statistical questions:

  • What color is the principal’s car?
  • Does Elena have a cell phone?
  • What kind of literature; fiction or nonfiction does Diego prefer?

(1.) How are the three statistical questions alike? What do they have in common?

(2.) How are the three non-statistical questions alike? What do they have in common?

(3.) How can you find answers to the statistical questions? How about answers to non-statistical questions?

(4.) What makes a question a statistical question?
