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 defined by
![y^{(\lambda)} = \left \{ (y^{\lambda}-1)/{\lambda}, if \lambda \neq 0; and \log{y}, if \lambda = 0 \right\}](/socr/uploads/math/f/1/f/f1f929d39bf753e427175f24715c4f31.png)
