As you have seen in several examples in class, we can understand a lot about a data set based on information that is given to us in a study about the central tendency and variation of a data set.

Describe the following terms in your own words:

• Mean
• Standard Deviation
• Z Scores
• Correlation

Finally, if someone told you that the average of a data set was 40, and that standard deviation was 10, what else could you derive from that information.
