Babatunde Olawoye Popular answer

For simplicity I would recommend Design Expert. It is so simple to use and understand when it comes to experimental design and data analysis. But constructing 3D surface plot and contour graph for the analysis I always use statistica 12.5. It has the best 3D surface plot, contour graph as well as Pareto chart. Someone can easily explain and understand the combine,effects of variables on their responses when using statistica than using Design Expert. If you are just learning experimental design using Response Surface Methodology, I would advice you to stick to Design Expert. Statistica is little bit complicated than Design Expert. If you want to understand more on how to use design expert, you can check my profile and click on research items you will find a comprehensive handout on how to use Design Expert for experimental design. Thanks

Design Expert is probably the most useful software as per DOE and RSM analysis, both theoretical and graphical, is concerned.

Contour and surface plots can also be generated in Matlab/Scilab.

Jyoti Divecha

MINITAB and Design-Expert are two software that features Response Surface Methodology (RSM). It consists of first planning a set of experiments, that is, selecting a Response Surface Design (RSD) first order followed by a second order RSD, secondly, obtaining the experimental data, and, upon collection of data, analysis of the design for modelling and prediction.

RSM cannot be applied to any experimental data.
