I am testing paint Film Adhesion. Measuring it in % of portions are peeled off in a test.
When I am saying the quality of paint in terms of Film adhesion, I have to say % of portions NOT peeled off. So % NOT peeled off = 100 - % of Peeled off.
While doing Taguchi analysis
For the first category (% peeled off) I am taking "Smaller is better"
Also I am trying it
for the Second (% NOT peeled off) I am taking "Larger is better"
The results of Analysis of variance
for Means both (peeled off, Not peeled off) gives same R sqr, Adj R sqr and F values
but for S/N Ratio both gives different R Sqr, Adj R Sqr, and F values
Can anyone please explain me Why it is so?
PS: I have attached the data and results.
Thanks
