# Explore Measures of Center

With a partner, continue working with the line plot, and answer the following questions:

- What happens to the mean if you add data points above the mean?
- What happens if you add data points below the mean?
- Can you add data both above and below the mean so that the mean does not change?
- What happens to the median if you add data points above the median?
- What happens if you add data points below the median?
- Can you add data both below and above the median so that the median does not change?
- Think about whether the mean would go up or down if you added a data point above the mean.
- If the mean is 6 and you add a data point at 4, where would you have to add another data point so that the mean does not change?
