## A Small Dataset

Ten values are plotted on a number line below.

Hover your mouse over each of the lines.

### Questions

- What is the mean of the ten numbers?

What is their median? - Describe what happens:

- Explain why the median doesn't change when you drag one point:

- Figure out how to get the median to change and explain what you did:

Click and drag one of the points.

## A Larger Dataset

This time one hundred values.

Experiment with dragging points, pay particular attention to the behavior of the lines for the mean and median.

### Questions

- How does the behavior of the mean when you drag one point in this large dataset compare with its behavior in the small dataset?

- How does the behavior of the median when you drag one point in this large dataset compare with its behavior in the small dataset?
