A constraints tool which allows you to exclude combinations of factors at a vertex that will not produce a useful or measurable response.An evaluation tool to check the overall design and errors,.A graphing tool to plot the data (Figure 1),.A summary of the design and results including some basic descriptive statistics,.A notes text box allowing you to add any useful comments.The second Information section shows the tools to evaluate the design and results including: The first section consists of the Design (Actual), which contains our data table. On the left-hand side of the Design-Expert dashboard is the navigator tree for the project. Now that you have set up your experiment and acquired your data, we can use Design-Expert software to analyse and interpret your results. We hope this basic step-by-step guide will help those of you starting out in the world of experimental design, whilst also acting as a useful tipsheet for attendees on our various DoE training courses. If you've not already read it, do explore our How-To: Set up a 2-level factorial design guide. In this How-To blog, we're going to walk you through the process of analysing a 2-level full factorial design using Design-Expert 13, a powerful DoE software package from Stat-Ease. You can download a 14-day free trial of this software here.
