There is no correct answer provided for this question among the answers below. This question has two parts, and most respondents address the first reasonably. For the second part (what kind of statistical analysis can/ cannot be performed with transformed data), the correct response is as follows - Process Stability and Capability Analysis can be carried out using transformed data. The control limits are also based on transformed data when using control charts. When using capability analysis, the specification limits are transformed too. Hypothesis testing is not done with transformed data but only with the original data. There are enough hypothesis tests (non-parametric tests) designed for non-normal data. Imagine comparing averages of two data sets transformed through Johnson's transformation. This would be meaningless because the two data sets would have been transformed with different equations (Johnson's transformation generates an equation to transform the data).

Q 582. One prefers the data to follow normal distribution, and if it does not, then we transform it to normal. Usually Box Cox transformation will work.

This was not an easy question to answer. It is pleasing to see several good answers. RSM is often associated with Box Behnken Design or Central Composite Designs, as these provide good models with limited runs (low cost). RSM also studies curvature in response surfaces very well. Gradient-based optimisation is key to RSM. The biggest benefit of RSM is that it requires limited experiments compared to full factorial experimentation. Avishi Mehta has mentioned most of these aspects; her answer is the best. (Some answers could not be approved because of AI-generated content.)
