Add two different data values to the set that will not affect the mean, median, or mode. Construct a histogram of the data, including the data values you added. Using a calculator, find the standard deviation of the data set, including the new values. Which values are within 1 standard deviation of the mean?

The data value 11.5 is farther from the mean than is the data value 11. The deviations 0.97 and 0.47 indicate that. A positive deviation occurs when the data value is greater than the mean. A negative deviation occurs when the data value is less than the mean; the deviation is -1.525 for the data value 9.
