SOCR Educational Materials - Activities - SOCR Power Transformation Family Graphing Activity

This is activity demonstrates the usage, effects and properties of the modified power transformation family using graphs of scatter plots

  • Background: The power transformation family is often used for transforming data for the perpose of making it more Normal-like. The power transformation is continuously varying with respect to the power parameter λ and defined for all y > 0 by:
y^{(\lambda)} = \left \{ (y^{\lambda}-1)/{\lambda}, if \lambda \neq 0; and \log{y}, if \lambda = 0  \right\}
  • Exercise 1: TBD
