how many questions did you answer correctly on the last statistics quiz?

Explanation:

To determine which question has the least variability, we analyze each option:

• "What score did you receive on your last statistics test?" : Scores can vary among students.
• "How many statistics teachers work at our school?" : The number of statistics teachers at a school is a fixed value (it doesn't depend on the individual student), so the answers will likely be the same for all 10 friends.
• "What is your quiz grade average in this statistics class?" : Quiz grade averages can vary among students.
• "How many questions did you answer correctly on the last statistics quiz?" : The number of correct answers can vary among students.

So the question about the number of statistics teachers at the school is least likely to have variability.

Answer:

B. How many statistics teachers work at our school?
