Working through the different statistical tests needed for a six sigma project. Specifically I am working throug the Six Sigma: a complete step by step guide circulated at the start of furlough and working through the statistical tests in python using Numpy and SciPy libraries.
Overview of code files:
- Measures of variability (range, variance, standard deviation, Bessel correction, long method, short method (pandas, numpy or Scipy))
- Standard scores/ z scores for capturing the difference between a value and the mean - A visual method, a simple calculation using pandas and finally using SciPy
