I am looking for suggestions on how to statistically compare products, not processes.
We manufacture springs that are the same length but have different widths and thicknesses. We are evaluating as-is and 1, 2, 3 hour heat treat. We want to compare these products with competitor products. There is only 1 finished specification/attribute: resistance.
I am looking for help writing a protocol to compare our different product to competitors. Initial testing shows some products have larger Std. and Ranges than the others but the Mean is much higher.
How do I evaluate benefits of a higher Mean compared to other products that have a much tighter range and/or Stddev?
