Data Analytics for Cyber Security

  • Probability for Normal Distributions
    • Normal (Bell-shaped) Curve
    • Standard Normal and Z-Scores
      • Standard Normal Distribution
        • Mean = 0
        • Standard Deviation = 1
        • N(0, 1)
      • Z-Scores
        • Z = (x – mean)/std dev
        • Example
          • Young women heights (inches)
          • N(64.5, 2.5)
          • Z-Score for woman 68 inches tall; Z = (68 – 64.5)/2.5 = 1.4
          • Z-Score for woman 60 inches tall; Z = (60 – 64.5)/2.5 = -1.8
          • Z-table
      • Empirical Rule Probabilities- 68-95-99.7
      • Normal Curve Calculations with Z-Scores
    • Why Normal Distribution is the most important distribution
