Qualitek-4 4.8

Qualitek-4 from Nutek, Inc. automatically designs experiments based on user-indicated factors and levels. The program selects the array and assigns the factors to the appropriate column. For more complex experiments, there is a manual design option. The program also performs the three basic steps in analysis: main effect, analysis-of-variance, and optimum studies. Analysis can be performed using standard or signal-to-noise ratios of results for smaller, bigger, nominal, or dynamic characteristics. Results can be displayed using pie charts, bar graphs, or trial-data-range graphs.
