Dear Henant,
many tanks for your Videos. It helped me a lot to understand DOE better.

Dear sir,
The video was very helpful. As a research student it helped me a lot in optimization part of my study. Thank you very much sir.

very useful DOE information, I have better understanding now

Thank you for the video. But I have one question. Is the data (response) required to follow any specific distribution like normal distribution here? If yes, then what if the data isn't normally distributed?

I am making a similar analysis and this video is helping me a lot. In my “yield” column should I use the mean of the samples I’ve taken? I have measurements of each combination (30 samples each) and don’t want to use only one data.

Hello sir,
Your videos are really helpful.
Can you please make a video on how to analyze and interpret fractional factorial design( 2^4-1) using DoE software. How to select factors that are significant from half normal plot without maintaining the hierarchy. Interpretation of interaction, contour and response surface plot.

Hello, I followed the exact same steps but my T and p value column has "*" in them and it says it couldn't calculate as MSE is zero and Degree of Freedom is zero . How do I fix this ? Please let me know.

this video is excellent. I insert 19 factors for 20 run and it keep show me this "Backward Elimination of Terms
α to remove = 0.1
The initial model was saturated. The stepwise procedure removed the following terms in order
to obtain sufficient degrees of freedom to begin: X4, X8, X10, X14, X16" could you please explain me why?

Hello! I have a question for a 2^4 full factorial design.The factors are A, B, C and D and I have values for 2 replicates.My problem is that I have seen some examples where they sum the values in one column and in other examples they put the values in different columns and proceed to the design using both as responses.Is there any difference in these two methods?Which one is correct? Thank you in advance!

Sir, any particular reason using fractional factorial doe... why not another method. which one is good method and easily get the final response optimizing result?

Dear sir, pl add what is the use of surface plot and contour plot .

rahulbachal

Hi, sir

I am an industrial engineering student. In my 2(5-1) experimental designs, it does not calculate t value and v value. What should I do? What is wrong?

Hello, Who has an idea how the "Yield" values used here were obtained? The values copied from the Excel file.
