Instructions for Teachers

Before this Activity

If needed, review the following terms and concepts:

• Mean – a measure of center in a set of numerical data, computed by adding the values in a list then dividing by the number of values in a list.
• Median – 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.
• Mode – The value that occurs most often in a data set.  A data set may have more than one mode, or may not have a mode at all.
