Statistical vs. a non-statistical question

What do the questions in your "statistical questions column" have in common?

What do the questions in your "non-statistical questions column" have in common?

What is the difference between the two types of questions?

A statistical question anticipates varied answers (variability). Example: What are the favorite colors of students in the school?

A non-statistical question has a single, definite answer. Example: How many days are in the month of March?

The answers to a statistical question are called data. Data is information such as facts and numbers that can be used to analyze something or make decisions.

There are two kinds of data:

Discrete data is data you can count. It only has specific, separate values, like whole numbers. For example, the number of students in a class or how many pets someone has. You can’t have 2.5 students or 3.7 pets!

Continuous data is data that can take any value within a range. It’s like measuring something that can be in between numbers, like how tall someone is or the temperature outside. You can have 5.3 feet or 72.8 degrees.

Examples of both kinds of data:

In your notebook, create two statistical questions.

The answers to one of the questions will result in discrete data (whole numbers).

The answers to the other question will result in continuous data (parts of a whole).

Refer to yesterday's assignment, the questions you wrote in your notebook, and share one of the statistical questions you created.

On the blank side, write: First name, last name, U1T1

What is the difference between a statistical question and a non-statistical question?

Write on the board:

Introduce the two types of data: discrete (whole numbers) and continuous (whole numbers and parts of a whole)

Use these examples:

You and your group are going to create statistical questions for a REAL SURVEY that we will be using to get to know each other.

Work with your group to create at least four statistical questions that will allow you to collect both kinds of data.

One person from your group, go to Google Classroom > our class > Classwork.

Click the link to share your group's two favorite statistical questions -- one that will result in discrete data (whole numbers) and another that will result in continuous data (whole numbers and parts of a whole)

In a moment, I will pass yesterday's entry ticket back to you.

The first thing you want to do is glue it into your notebook. It is one of your learning archives.

Secondly, let's review some Level 3 work and discuss. If you scored a 1 or a 2, you are welcome to revise your original answer -- but I encourage you to leave your original answer (don't erase it, simply put a line through it and write your revised answer above, below or next to it)

I do make mistakes! Please check PowerSchool to verify that the number on your entry ticket is the same number I entered in PowerSchool.

Great job of creating statistical questions yesterday! I used your submissions to create our Get to Know Your Class Survey Part 1.

* Bonus: how do you know that the questions in this survey are statistical questions?

Here is the data we collected!
