I'm currently performing a real bench experiment that would essentially validate the results of those generated in two different computer models. Essentially, there is one (real) test setup, one computer model, and another (but different) computer model. I have ONE result from each of the tests, so in total I have three numbers. The real test setup and one of the computer models are similar to each other at 2.70 and 2.71, respectively. The other computer model is 2.80. I want to see if the last computer model result of 2.8 is "acceptable" or falls "within range" of the other results. I was told to use error bars, but I'm not sure if this would be the best approach.
