Unit 12 - Statistics 3 - Normal Distribution

Unit Objectives
  • Understand the concepts of random variables and parameters μ and σ [4.1]
  • Recognise and use property of symmetry about x=μ [4.1]
  • Represent problem in a sketch [4.1]
  • Use GDC to find probabilities using Normal Distribution [4.1] (Video 12.1)
  • Use GDC to solve inverse Normal Distribution problems [4.1] (Video 12.2)
  • Calculate the expected value [4.1]
  • Know that approx. 68% of data lies within μ ± σ, 95% lies within μ ± 2σ, and 99% lies within μ ± 3σ. [4.1] (Video 12.4)
