Lesson 6.8: Rising Temperatures Across
the United States

2. Lesson 6.8 Objectives
By the end of this lesson, you should understand that:
Standard deviations can be used to determine how extreme an unusual value is in a data set.
Standard deviations can be used to compare different data sets.

3. Lesson 6.8 Objectives
By the end of this lesson, you should be able to:
Use a spreadsheet to compute the mean and standard deviation of a data set.
Use the standard deviation to describe the spread of a data set.
Use the mean and standard deviation to describe how extraordinary a single datum (data point) is.
Use the means and standard deviations of multiple data sets to compare data values between these two datasets.

4. Lesson 6.8 Connections Main ideas in the lesson:
Knowing the mean (or median) of a data set is a first step in understanding a data set. In many cases, the variability of the data set is equally important.

5. Lesson 6.8 Connections Connections to the 8 course goals:
2. Reason abstractly and quantitatively.
5. Use appropriate tools strategically.
7. Look for and make use of structure.
