   Question

   Why is the standard deviation (the standard deviation) often preferred preferred over the range (the range) as a measure of variability?

   
   
   1. FALSE: He range (the range) does not look at the ends of the distribution, but the standard deviation does.
   2. TRUE: The range (the range) only looks at the ends of the distribution, and the standard deviation is based on all observations.
   3. FALSE: The range (the range) looks only at the middle of the distribution, and the standard deviation looks at the entire distribution.
   4. FALSE: The range (the range) expresses variability in a non-standardized way, while the standard deviation is based on z-scores.
   
   
   1. False
   2. True
   3. False
   4. False
