1. Answer the following questions to summarize this module:
   1. The standard deviation basically calculates the average distance each observable item of data is away from the mean. True or False.
   2. The standard deviation is used to understand whether or not we should use the mean or the median to describe the central tendency of the data. Dividing the standard deviation into the mean creates a coefficient of variation. True or False.
   3. A coefficient of variation that is over .30 shows that the mean is rather meaningless, and the median instead should be used to describe the central tendency of the data. True or False.
   4. Other good measurements of dispersion involve the range, and simply stating the high and the low ends of data. True or False.
