Lesson 1.5: Asking Statistical Questions

​Lesson 1.5: Asking Statistical Questions

By Ms. Wiley

This Wayground lesson is a part of our Week #2 Practice Problems grade.

Objective for Today

I can recognize a statistical question by checking if it expects variability in the answers.

What Makes a Question Statistical?

Poll

Which of these would be more interesting to ask your classmates?

• Do you have a pet?

• How many pets does each student in our class have?

A question that expects different answers, not just one. Statistical questions use data to find patterns or summaries.


Example: "How many pets does each student in our class have?"

This is statistical because everyone might have a different number of pets.

​

​Statistical Question

The difference in the data - not everyone answers the same.




In our example, some students might have 0 pets, others 1, 2, or more.

That's variability - and it's what makes a question interesting for data collection!
