Cumulative Standard Normal (Z) Distribution

  • NOTE:  There is usually a diagram that accompanies this type of table that is critical to interpretation.
  • NIST - Cumulative Distribution Function of Z        Pr[0 < x < |a|]
  • StatSoft - Standard Normal (Z) Table                  Pr[0 < x < |a|]
  • UCLA - Standard Normal Cumulative (Z) Table    Pr[x < -a]  and Pr[x > a]  Different Formats (left tail, right tail) 
  • Demonstrate the concept of the 'pivot' to obtain Z in the probability statement.
