# Lesson 4

The Shape of Data Distributions

- Let’s explore various shapes of data.

### 4.1: Math Talk: Number Line Distance

Mentally, find the distance between the two values on a number line.

- 70 and 62

- 70 and 70

- 70 and 79

- 70 and 97

### 4.2: Suspicious Descriptions

For each picture and description:

- Do you agree or disagree with the description?
- If you agree, explain how you know it is correct.
- If you disagree, explain the error and write the correct description. Explain how you know it is correct.

### 4.3: Whipping Data into Shape

Describe the shape of each distribution using the terms approximately, symmetric, bell-shaped, skewed left, skewed right, uniform, or bimodal. Estimate the center of each distribution.
