# Summary of the Math: The Mean and Describing Data

**Read and Discuss**

: A measure of center in a set of numerical data, computed by adding the values in a list and then dividing by the number of values in the list.**Mean**: A measure of center in a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list, or the mean of the two central values, if the list contains an even number of values.**Median**: A measure of center that occurs the most often in a data set. There can be more than one mode, or none at all.*Mode*: The difference between the least and greatest values in a data set.*Range*

## Hint:

Can you:

- Describe what the mean is and how to calculate it?
- Describe what the median is and how to find it?
- Describe what the mode is and how to find it?
