     Normal Distribution
      There are many cases where data tends to 
      be around a central value with no bias left 
      or right.  This is called a Normal 
      Distribution.
      The “Bell Curve” is a Normal Distribution.
      It is often called a “bell curve” because it 
      looks like a bell.
      The Normal Distribution has 
      mean = median = mode.
     Advantages to using a bell curve: readily displays the mean/median, 
     easy to see spread, good for symmetric data
     Disadvantages to using a bell curve: only best for symmetric but not 
     skewed data, don’t know the specific data / individual data points
      Standard Deviation
       The standard deviation is a measure of how spread out numbers are.  
       Generally, this is what we find out:
           68% of values are           95% of values are          99.7% of values are
