t-Test

BagingBison2009 — Mon, 28 Oct 2024 16:17:06 GMT

I want to set up a t-Test that proves the new process is equivalent OR better than the current process. How do I do that in JMP?

Have a read of this article: https://community.jmp.com/t5/JMP-Blog/Need-for-Speed-ANOVA-and-comparing-means/ba-p/739489

That should guide you on how to apply means comparisons

Please see the JMP documentation about equivalence tests in the Oneway platform (Analyze > Fit Y by X).

When I perform the equivalence test, all 3 p-values are greater than 0.09. Therefore, I do not have enough evidence to prove X is better than Y, Y is better than X, or that they are equivalent.

That conclusion (without seeing the actual test you performed and the resulting report) is correct.
