**Warmup**

**Activity #1**

**Data Visualization**

- This sketch shows ten data points with value between 0 and 20.
- Try other 10 data points by using the table on the right.
- Make it so it’s ten different data points.
- Change some values (but keep all ten different) to make the other one higher.

**Activity #2**

`Enter Data in a Boxplot.`

- Enter your data one element at a time in the curly brackets in the input box below.
- Once you have entered all your data, drag the red boxplot to match your data.
- Check your boxplot when finished!

**Activity #3**

`Exercise Questions.`

- For each question, decide if the responses will produce numerical data or categorical data and give two possible responses.

(1.) What is your favorite breakfast food?

(2.) How did you get to school this morning?

(3.) How many different teachers do you have?

(4.) What is the last thing you ate or drank?

(5). How many minutes did it take you to get ready this morning—from waking up to leaving for school?
