Overview for Johnson Transformation

Use the Johnson Transformation to transform your data to follow a normal distribution using the Johnson distribution system. Using this analysis, you can do the following:

  • Determine whether the original and transformed data follow a normal distribution.
  • Store the transformed values in the worksheet.

For example, a quality analyst wants to perform a statistical analysis that assumes that data follow a normal distribution. The process data may not be normally distributed, so the analyst uses the Johnson transformation to check the normality of the original data, transform the data, and verify that the transformation is effective. The analyst also stores the transformed values in the worksheet for further analysis.

Where to find this analysis

To perform a Johnson transformation, choose Stat > Quality Tools > Johnson Transformation.
